Book cover of Ecotopia

Catherine V. Wolf Author Of The Drum Tree

From my list on eco-fantasy books with forests and gardens.

Why am I passionate about this?

I love our planet. That’s the long and short of it. I have stretched belly-down upon the earth and hugged this whole world as if it is an extension of myself, or I am an extension of it. We are one, as I think we all are, with this world that is our home. After receiving my Master's in Nature Study and Environmental Education, I taught grade school for many years, spending as much time outside with the students as I could. At the same time, I have been writing stories and loving nature, loving our world, and working on stewardship. Eco-fantasy is a genre that just seems natural to this mission. 

Catherine's book list on eco-fantasy books with forests and gardens

Catherine V. Wolf Why Catherine loves this book

This was one of the first books to open my mind to the possibility of a country that would put social responsibility and ecological sustainability at the forefront of its goals.

Ernest Callenbach’s story is told through the journalist reports and personal writings of William Weston, who visits Ecotopia to report on this unique country, originally the Pacific Northwest and Northern California.

I love how Weston’s skepticism turns toward understanding. He eventually embraces what Ecotopia stands for and decides to live there himself to be a conduit of connection to the world outside of Ecotopia.

I was so moved by how a fictional story could so illuminate our own fears, our own hopes, and the possibilities of our future, that my own writing turned toward eco-fantasy after reading this book.

What is this book about?

Twenty years have passed since Northern California, Oregon, and Washington seceded from the United States to create a new nation, Ecotopia. Rumors abound of barbaric war games, tree worship, revolutionary politics, sexual extravagance. Now, this mysterious country admits its first American visitor: investigative reporter Will Weston, whose dispatches alternate between shock and admiration. But Ecotopia gradually unravels everything Weston knows to be true about government and human nature itself, forcing him to choose between two competing views of civilization.Since it was first published in 1975, Ecotopia has inspired readers throughout the world with its vision of an ecologically and socially…

Book cover of Daughter of the Empire

Daniel Rirdan Author Of Republic of Forge and Grace

From my list on worlds you’ll actually want to live in.

Why am I passionate about this?

Ever since high school, I've been passionate about societies, communities, and institutions that allow true prosperity to emerge—in one fashion or another. This thread runs through all my writing—both fiction and nonfiction. And what I’ve found is that a sense of well-being can wear many social guises. 

I built this list because portraying worlds worth living in appeals to me endlessly more than immersing in bleak ones.

What moved me is how much it means to belong to the Acoma estate.

Nacoya with her sharp wisdom, Keyoke with his unyielding honor, Arakasi with his chosen allegiance, even the grey warriors—they all belong to something bigger than themselves. When danger hits, the fear ripples through everyone. When triumph comes, it lifts all of them.

A big draw of the book was seeing people pull together not because they’re supposed to, but because they genuinely care. The Acoma isn’t just a political house; it feels like a place where being needed gives everyone a kind of quiet dignity.

What is this book about?

From the imagination of two of fantasy's greatest names comes a magnificent epic of heroic and dynastic struggle.

At age 17, Mara's ceremonial pledge of servantship to the goddess Lashima is interrupted by the news that her father and brother have been killed in battle on Trigia, the world through the rift.

Now Ruling Lady of the Acoma, Mara finds that not only are her family's ancient enemies, the Minwanabi, responsible for the deaths of her loved ones, but her military forces have been decimated by the betrayal and House Acoma is now vulnerable to complete destruction.

Daniel Rirdan Why Daniel loves this book

I felt awe-struck stepping into Gaea’s hollow world—where zeppelin-sized blimps glide through a sky inside the giant, planet-like being, and forests and rivers hang overhead. Gaea feels both grand and intimate: cathedral-scale biology paired with tavern-table camaraderie. 

And then there are the titanides. Their society feels hand-tooled—full of music and unpretentious sensuality. No posturing, no greed, just beings who live in balance. The centaur-like titanides dwell beneath a colossal tree hung with lanterns… and it all feels alien and warm and cozy and wonderful.

Daniel Rirdan Why Daniel loves this book

Mammoths grazing outside the protagonist’s dwelling—yeah, that was love at first sight.

And the lived-in environment? Homes carved into colossal, cultivated trees, and people served by public, stackable electric vehiclesyes, please. The land thrives, and no species has been driven to oblivion.   

Sawyer’s parallel-Earth Neanderthals truly appealed to me: the emotional restraint, the honesty, the structural elegance of their culture. Even their norms around maintaining a sustainable population are handled with startling clarity—seasonal, communal parenting. 

No prisons, no poverty, no religion weaponized into hierarchy. Life runs on calm confidence, as if evolution took a gentler branch, and societyas it’d scaled upmanaged to keep its soul.

Robert J. Sawyer, the award-winning and bestselling writer, hits the peak of his powers in Humans, the second book of The Neanderthal Parallax, his trilogy about our world and parallel one in which it was the Homo sapiens who died out and the Neanderthals who became the dominant intelligent species. This powerful idea allows Sawyer to examine some of the deeply rooted assumptions of contemporary human civilization dramatically, by confronting us with another civilization, just as morally valid, that has made other choices. In Humans, Neanderthal physicist Ponter Boddit, a character you will never forget, returns to our world and…


Book cover of The Rise of the Polish Monarchy: Piast Poland in East Central Europe, 1320-1370

William L. Urban Author Of Teutonic Knights: A Military History

From my list on medieval Baltic history.

Why am I passionate about this?

I became enthusiastic about the history of the Baltics when my dissertation advisor persuaded me to use my language training in German and Russian to test the American Frontier Theory in the Baltic region. None of the various theories were applicable, but I earned a Ph.D. anyway. Later I taught in Italy, Yugoslavia, Estonia, and the Czech Republic. I've written a number of books and won a Fulbright Hays grant, the Dr. Arthur Puksow Foundation prize, the Vitols Prize, and others. I retired in 2017 after fifty-one years of university and college teaching, but I would still be teaching if my hearing had not deteriorated to the point that I could not make out what shy students were saying. 

William's book list on medieval Baltic history

William L. Urban Why William loves this book

The history of the Baltic Crusade cannot be understood in isolation from the Polish kingdom. This is the era when Poland recovers from the disasters begun by the Mongol invasions of the 1240s and begins its own eastward expansion.

As the title indicates, this is really the story of Casimir III, whose father arranged a Lithuanian marriage that brought peace on the eastern frontiers and later allowed him to expand toward Rus’ (especially Ukraine) when the minor states there collapsed. Casimir succeeded in everything except siring a legitimate male heir, even though that was the one task expected of every monarch in this era. He did leave behind a flourishing state, a powerful church, and a national goal of driving back those Germans (especially the Teutonic Knights) who had made great inroads into areas claimed as the national patrimony.

William's book list on medieval Baltic history

William L. Urban Why William loves this book

This is a provocative book. Its very title suggests how difficult it is to understand Polish history than other that a divine joke. Yet his scholarship is excellent and his insights enlightening.

This is especially true for the first volume, which deals with the emergence of the Polish kingdom from rude barbarism to a political and cultural force so powerful that, after its union with Lithuania, dominated East Central Europe for generations. The total collapse of the kingdom in the 18th century—largely to defects in the constitution that allowed foreign interference in the election of the king—has blinded us to what Poland achieved in those forgotten centuries.

What is this book about?

The most comprehensive survey of Polish history available in English, God's Playground demonstrates Poland's importance in European history from medieval times to the present. Abandoning the traditional nationalist approach to Polish history, Norman Davies instead stresses the country's rich multinational heritage and places the development of the Jewish German, Ukrainian, and Lithuanian communities firmly within the Polish context. Davies emphasizes the cultural history of Poland through a presentation of extensive poetical, literary, and documentary texts in English translation. In each volume, chronological chapters of political narrative are interspersed with essays on religious, social, economic, constitutional, philosophical, and diplomatic themes. This…

Book cover of The Trumpeter of Kraków

Andrew Beattie Author Of The Angel Player

From my list on middle grade children’s books set in the Middle Ages.

Why am I passionate about this?

I was an author of history and travel books before turning to children’s fiction. My books for the publishers Pen and Sword tell the stories of the places associated with the Princes in the Tower, the boys who mysteriously disappeared from the Tower of London during the reign of King Richard III, and King Arthur, the semi-mythical King of the Britons during the Dark Ages. So it was obvious that I should use my passion for medieval history when it came to deciding on a setting for my collection of upper middle grade children’s novels. I hope readers enjoy reading them as much as I have enjoyed researching and writing them!

Andrew's book list on middle grade children’s books set in the Middle Ages

Andrew Beattie Why Andrew loves this book

I am a travel writer as well as a children’s author and the Polish city of Kraków (or Cracow) is one of my favourite destinations in Europe, and one I have written about too.

Its ancient buildings mean that it’s a place where the medieval era comes alive, and that’s why I loved this book, which is written by an American professor of English who had a life-long love of Poland and its people.

Set in 1461 it tells the story of a boy named Joseph Charnetski who is thrillingly caught up in plots and intrigue (featuring alchemists and hypnotists along the way) when his family seeks sanctuary in the city.

1 author picked The Trumpeter of Kraków as one of their favorite books, and they share why you should read it. This book is for kids age 8, 9, 10, and 11.

What is this book about?

For well over thirty years, Eric P. Kelly's Newbery Award winner has brought the color and romance of ancient times to young readers. Today, The Trumpeter of Krakow is an absorbing and dramatic as when it was first published in 1928.

There was something about the Great Tarnov Crystal...Wise men spoke of it in hushed tones. Others were ready to kill for it. Now a murderous Tartar chief is bent on possessing it. But young Joseph Charnetski was bound by an ancient oath to protect the jewel at all costs.

When Joseph and his family seek refuge in medieval Krakow,…


Book cover of My Sister's Mother: A Memoir of War, Exile, and Stalin's Siberia

Katrina Shawver Author Of Henry: A Polish Swimmer's True Story of Friendship from Auschwitz to America

From my list on Poland and it's people during World War 2.

Why am I passionate about this?

I am an author, lifelong history geek, and relentlessly curious about finding unknown stories. In 2002 I met Henry Zguda, an eighty-five-year-old Polish Catholic who survived three years in Auschwitz and Buchenwald during World War II. He lived a mile from my house. Intrigued, I soon offered to write his incredible story. I am not Polish and knew little of Poland or Polish history when I began. This led to over ten years of research on Poland, World War II, and the Holocaust. My friendship with Henry changed the direction of my life and gave me keen insight into the plight of Poles, both Jewish and Christian, during World War II. Thousands of memoirs and books exist on the Holocaust. I believe the inspiring stories of Poles and other victims of Hitler and Stalin deserve equally widespread recognition.

Katrina's book list on Poland and it's people during World War 2

Katrina Shawver Why Katrina loves this book

My Sister’s Mother is a family memoir set against the backdrop of forced evictions and deportations of Poles to forced labor camps in frozen Siberia. Russia invaded Poland two weeks after Germany did, and the two powers divided Poland between their countries. Soviet communists murdered thousands of Polish citizens, Polish military, and in 1940 deported hundreds of thousands of civilian Poles, in freezing cattle cars, to forced labor camps in Siberia.

Urbikas’ mother and older sister faced impossible circumstances imposed by Stalin’s brutal policies against Poles. The core theme focuses on motherhood, the relationship between a mother and her daughter, and how far a woman will go to survive and protect her child. Then, the story transitions into the epilogue of war for thousands of Poles: life in a displaced persons camp and growing up with inherited trauma and the challenges common to first-generation Polish immigrants.

What is this book about?

In the 1950s, baby boomer Donna Solecka Urbikas grew up in the American Midwest yearning for a ""normal"" American family. But during World War II, her Polish-born mother and half sister had endured hunger, disease, and desperate escape from slave labor in Siberia. War and exile created a profound bond between mother and older daughter, one that Donna would struggle to find with either of them. In this unforgettable memoir, Donna recounts her family history and her own survivor's story, finally understanding the damaged mother who had saved her sister.


Book cover of Poland

Carly Schabowski Author Of All the Courage We Have Found

From my list on WWII that shed light on Polish history.

Why am I passionate about this?

My passion for writing historical fiction set mainly in Poland, or including Polish protagonists is born from my own familial history. My grandfather was forced into the Wehrmacht as a young man, who managed to escape to the UK and join the Polish Army in exile, eventually going back to fight against the Germans. His story set me on a course to become a historical fiction author; reimagining the past and bringing little-known stories to a wider audience. I find that the best way to gain a basic understanding of Polish life during WWII is to read widely – try historical accounts, memoirs, second-hand accounts, and of course, historical fiction.

Carly Schabowski Why Carly loves this book

Poland is a historical novel that spans Polish history all the way back to 1240, and continues on to cover various years, including WWI, WWII, and up to the early 1980s. The book is centered around three interconnected families throughout this investigation into their pasts, and is a must-read in terms of truly understanding and getting an authentic view into Polish lives throughout the ages. I feel that this book is a stand-out in terms of the authenticity it achieves.

“A Michener epic is far more than a bedtime reader, it’s an experience. Poland is a monumental effort, a magnificent guide to a better understanding of the country’s tribulations.”—Chicago Tribune

In this sweeping novel, James A. Michener chronicles eight tumultuous centuries as three Polish families live out their destinies. The Counts Lubonski, the petty nobles Bukowksi, and the peasants Buk are at some times fiercely united, at others tragically divided. With an inspiring tradition of resistance to brutal invaders, from the barbarians to the Nazis, and a heritage of pride that burns through eras of romantic passion and courageous solidarity,…

Book cover of Poland's Holocaust: Ethnic Strife, Collaboration with Occupying Forces and Genocide in the Second Republic, 1918-1947

Antonio J. Muñoz Author Of Nazi Occupation Policies in the East, 1939-1944

From my list on the Holocaust and the Nazi Occupation of Eastern Europe.

Why am I passionate about this?

I’m a Cuban refugee. I came with my family in the early 1960s a few years after the Cuban revolution. I served 4 years in the U.S. Marines. I went to school and in 1982 married. Both of my daughters became college professors. The younger works for the CUNY system, while the oldest teaches at Yale University in New Haven, Connecticut. I have always had a passion for modern European history. It grew from an interest in military history when I was a Marine.

Antonio's book list on the Holocaust and the Nazi Occupation of Eastern Europe

Antonio J. Muñoz Why Antonio loves this book

There are far fewer studies in English on the Nazi occupation of Poland and the suffering and depredations that Poles faced during those more than five years of occupation.

This academic study does not merely cover the Holocaust in Poland but how the occupation affected millions of non-Jewish Poles as well. It also covers the intricate relationship that existed between Poles and Ukrainians, Lithuanians and Belorussians, and how those ethnic differences turned into conflicts that affected the war and the occupation. It is a one-volume work that covers it all.

With the end of World War I, a new Republic of Poland emerged on the maps of Europe, made up of some of the territory from the first Polish Republic, including Wolyn and Wilno, and significant parts of Belarus, Upper Silesia, Eastern Galicia, and East Prussia. The resulting conglomeration of ethnic groups left many substantial minorities wanting independence. The approach of World War II provided the minorities' leaders a new opportunity in their nationalist movements, and many sided with one or the other of Poland's two enemies - the Soviet Union and Nazi Germany - in hopes of achieving their…
