Book cover of Harper Wells

Debra Clewer Author Of The Secret Gold

From my list on time-slip adventures for middle graders.

Why am I passionate about this?

An avid reader since the age of 7, I have long loved history. When combined with fiction and throwing in a time slip, my imagination is unlimited! I have a passion for introducing historical fact to young readers, and time-slip adventure is a fun and engaging way to do it, without being bogged down with superfluous information. Young people’s reading levels have changed (as recent statistics worldwide show). As a writer, I gain inspiration from these novels for my own works.

Debra's book list on time-slip adventures for middle graders

Debra Clewer Why Debra loves this book

I love history and found this to be an engrossing, historically based time-slip novel. 

From reading this, I learned about the politician, social reformer, and feminist Edith Cowan. The author has woven a cast of supporting characters to add to the story’s depth. 

I particularly love the inclusion of the time-travelling bed, which holds its own secrets. It’s an interesting twist on the usual time-travel methods, and instrumental to the historical fiction story's timeline.

Debra's book list on time-slip adventures for middle graders

Debra Clewer Why Debra loves this book

This is an epic adventure of boldness and bravery, and I loved the character of Nerra, who is thrust into an important role, where she finds a new maturity.

I have long been interested in First Nations folklore, and this one kept me reading. The relationship between the girl and her great-grandmother is endearing to me as one who was largely raised by my maternal grandmother.

Nerra is a wonderful protagonist who learns to be brave and resilient along the way, as she tackles the serious task of saving the keepers of the rainbow, finding a new maturity along the way.

Debra's book list on time-slip adventures for middle graders

Debra Clewer Why Debra loves this book

This is an engrossing time-slip story with a difference. 

Involving two countries, two different timelines, four very different lives, and the English royal family in the Second World War, I was taken by the way the narrative interchanges seamlessly between the 1941 and 2022 time periods to create an action-filled MG story. 

The completely different character arcs of two boys who form a strong bond, taking two others along with them, are compelling. I also love the way the historical information side is well researched, providing knowledge I didn’t previously have.

Brace yourself for the time-travel adventure of two lifetimes!

Jett was just happy to make a new friend.

He honestly didn’t mind that Harry claimed to have time travelled via a secret underground tunnel from wartime London all the way to twenty-first century New Zealand.
Nothing wrong with a kid having a great imagination.

Except Harry wasn’t lying or making it up.
There really was a tunnel.
An impossible link between the past and the future.
But tampering with time travel, even by accident, has unintended consequences.

Now Harry and Jett have to race against time to mend what was…

Debra's book list on time-slip adventures for middle graders

Debra Clewer Why Debra loves this book

This is a great time-slip adventure story.

I love the author’s deep knowledge of Australian dinosaurs and the research she has put into creating a fast-paced and riveting story. Zac, Clare, and Luke Adamson are in drought-stricken outback Queensland. When the trio set off in search of dinosaur fossils, two cyclones merge, and after the storm clears, they are in a vastly different place and time. 

From reading this, I discovered something new and learned about an ancient creature known as the Demon Duck of Doom. Very interesting stuff indeed!

Book cover of The Red Lion: The Elixir of Eternal Life

Viktoria Duda Author Of Twenty-Five Centuries Without You

From my list on spiritual adventure books to open new doors to your consciousness.

Why am I passionate about this?

I am a writer, a hypnotherapist, and a consciousness researcher. Ever since I was a baby, I had the memory and the sense that there was more to our existence than meets the eye. Even though I started my career as a lawyer in Vienna, Austria, after a transformative illness and a series of spiritually awakening experiences, I left for Mexico to pursue my calling as a metaphysical explorer and writer. Ever since, I’ve spent my life mapping out various dimensions of the psyche. When I’m not traveling, I like to retreat into my small highland cottage with Marius, the border collie, and Kasiopea, the black magic cat.

Viktoria's book list on spiritual adventure books to open new doors to your consciousness

Viktoria Duda Why Viktoria loves this book

With this Hungarian author, I share the same birthday, as well as our mystical philosophy on life. Her book is an epic alchemical tale spanning centuries that describes the evolution of consciousness through subsequent incarnations from one life to the next.

I find not only the book itself fascinating but also the story of how it came into being. The author began to write it in a bomb shelter during WWII. Afterward, the Communists banned it and burned it, yet a few copies were miraculously rescued and hand-copied during dictatorial times.

Today, the book enjoys cult status in its homeland of Hungary. Unfortunately, the English translation is currently out of print, but if you can lay your hands on a version you can read, don’t miss out on this masterpiece.

2 authors picked The Red Lion as one of their favorite books, and they share why you should read it.

What is this book about?

Conceived amidst the horrors and hellfire of the Second World War, Mria Szepes' novel about a man's search for the Elixir of Life offered a glimpse of hope at a time of con-flagration. By giving a broad cosmic perspective to the events touching the lives of everyone in Europe in those years, she put human existence in a broader scale extending beyond daily life and put forth a reason for existence within the entirety of the Universe. After the war this remarkable book was published in Budapest but was soon banned by the government. Following decades of hibernation, like the…


Book cover of The Hero of Budapest: The Triumph and Tragedy of Raoul Wallenberg

Monica Porter Author Of Deadly Carousel: A Diva’s Exploits in Wartime Budapest

From my list on the Holocaust and the stories of victims and heroes.

Why am I passionate about this?

I was 12 years old when, in Amsterdam on a family holiday, I was taken to see the Anne Frank House. Until then I knew very little about WW2, the Nazis, and the Holocaust. After viewing the ‘secret annexe’ my father bought me The Diary of Anne Frank, which was on sale there, and I started reading it in the car as we drove off. The book sparked my deep lifelong interest in that chapter of history. Many years later I discovered that my own mother also had an extraordinary wartime story. By then I was a journalist and knew I’d have to write a book about it—Deadly Carousel.  

Monica's book list on the Holocaust and the stories of victims and heroes

Monica Porter Why Monica loves this book

For me (and not just because my family is Hungarian), Wallenberg’s story is the most heart-wrenching of all accounts of Holocaust heroism. He was the Swedish diplomat in Nazi-occupied Budapest who worked tirelessly to save Jewish lives, despite death threats to himself. He issued thousands of Swedish protection documents and set up Jewish safe-houses. One incident particularly brings a lump to my throat. Hearing of a death march of Jewish deportees, he drove to the Hungarian border to head it off. Clutching a bunch of Swedish passports, he ordered the Arrow Cross guards (Hungarian fascists) to stand aside whilst he searched for the Jews entitled to them. The suspicious guards surrounded him with pointed bayonets, but he shouted above their heads that he had passes for anyone who had ‘lost’ them. Hands were raised throughout the crowd. Wallenberg was so convincing that the SS officer in charge finally relented. The…

What is this book about?

The story of Raoul Wallenberg - the Swedish businessman who, at immense personal risk, rescued many of Budapest's Jews from the Holocaust and subsequently disappeared into the Soviet prison system - is one of the most fascinating episodes of World War II. Yet the complete story of his life and fate can only be told now - and for the first time in this book - following access to the Russian and Swedish archival sources, previously not used. Born into a wealthy Swedish family, Wallenberg was a moderately successful businessman when he was recruited by the War Refugee Board to…

Book cover of Journey to a Revolution

Eileen Kay Author Of Hope, Laughter, Survival on the Refugee Trail

From my list on memoirs with a gutsy, life-changing journey.

Why am I passionate about this?

My version of a gutsy life journey was to find work abroad, buy a one-way ticket, and not look back - one place after the next. Long ago, girls didn’t do this, but I did. A struggle and worth it. Great memoirs have a geographical and an inner journey. They make me laugh and cry, both. This is what I love to read, and it’s my aim as a writer. My books are love letters to these adventures, plus some joking around in order not to scream or weep at some of what’s out there. I’ve been a teacher, a film editor, a comedian, a librarian, and now a writer.

Eileen's book list on memoirs with a gutsy, life-changing journey

Eileen Kay Why Eileen loves this book

He tells half of this history as an expert, the other half as an idiot.  

He and other naïve British students in 1956 were told by an uncle, “You need a war. We had Spain. You can have Budapest.” They drove to Hungary when everyone else was leaving that nightmare. They did not know what they were getting into, but soon found out. 

He’s witty and honest about their foolishness. But once there, he started writing about the street warfare he witnessed. It was the start of his career as a journalist and author. 

Korda is a proper historian - objective, clear, intellectual and cool. He’s also a witty entertainer, with a great line in classically British ironic understatement. He makes history dramatic and huge, yet also engagingly personal.

1 author picked Journey to a Revolution as one of their favorite books, and they share why you should read it.

What is this book about?

"Journey to a Revolution" is at once a history and a compelling memoir, the story of four twenty-four year old Oxford undergraduates who took off for Budapest in a beat-up old Volkswagon convertible in October 1956, to bring badly needed medicine to the Budapest hospitals and to participate, at street level, in one of the great, heroic battes of post-war history. Korda paints a vivid and richly detailed picture of the events and the people, explores such major questions as the extent to which the British and the American intelligence services were involved in the uprising and made the Hungarians…


Book cover of The Navigator's Daughter

Arthur Coburn Author Of Murder in Concrete

From my list on women facing dark and dangerous obstacles.

Why am I passionate about this?

I am an ex-lawyer, ex-army officer, and ex-Hollywood film editor who loves stories about females in danger who dig deep to solve problems and survive. I can’t claim to be an expert, but I marvel at the breadth of female styles–from delicate, feminine, and sweet to brave, adventuresome, and tough. I have edited films about various women characters, from Charlize Theron’s killer in Monster to Cate Blanchett’s spiritual medium in The Gift and Diane Lane’s brave romantic survivor in Under the Tuscan Sun. I have three successful step granddaughters: an accountant, a lawyer, and one getting a PhD in computer studies. Smart, talented, and interesting women people in my life.

Arthur's book list on women facing dark and dangerous obstacles

Arthur Coburn Why Arthur loves this book

As an infantry veteran, I felt especially drawn to the daughter’s loyalty and love of her dad; I shared her passion for exploring his diaries and traveling to the places in Hungary he described when his bomber was shot down in WWII.

I was thrilled at each stage of the daughter’s search for her dad near Budapest, and I tensed as she tried to decide which locals were on her side and which were out to deceive or harm her. I loved her passion to find the woman who had saved her dad’s life and I marveled at the wonders and charm of the two halves of the city, split by the Danube.

Why am I passionate about this?

I’m a voracious reader, an author, and also a book critic, so hundreds of books cross my desk. What I love the most is the feeling of discovery—reading a book whose likes I haven’t seen on any bestseller list or on a front display in a bookstore. There are so many, many hidden gems—books that have stayed with me long after the publication day, and I always want others to have the same devotion to them that I do!

Caroline Leavitt Why Caroline loves this book

Strangers in Budapest is exotic, gorgeous, and like a beautiful orchestra on paper. It also keeps you turning the pages.

A young American couple move here with their baby son after the fall of the Communists, but they bring their ghosts with them, and assimilating is difficult. especially when they encounter an elderly Jewish-American veteran, who has come to Hungary to exact revenge on someone he is convinced married and then murdered his daughter.

Book cover of This Rebel Heart

Lyn Miller-Lachmann Author Of Torch

From my list on for tweens and teens on Russian/Soviet aggression.

Why am I passionate about this?

I’m the author of multiple middle grade and YA historical novels, including Torch, which won the 2023 Los Angeles Times Book Prize for Young Adult Literature. Torch takes place in the aftermath of the Soviet invasion of Czechoslovakia in 1968, and it is especially timely in the face of the recent Russian invasion of Ukraine. The Bear (a popular symbol of the Russian Empire) has mauled many of its neighbors in the past century, not only Czechoslovakia and Ukraine but also the Baltic countries that, like Ukraine, were incorporated into the Soviet Union and the other Eastern European countries that were part of the Soviet bloc until the fall of Communism in 1989.
