Book cover of Slaughterhouse-Five

Stefan Bogdanski Author Of All the Shadows

From my list on apocalypse being dark times, but it‘s not the end (and might be fun, too).

Why am I passionate about this?

I‘ve been thinking about the forces that drive humanity together and pull us apart at the same time since my late teens; back then, I started reading the classical dystopian tales. The (perceived) end of time always speaks to me, because I think it‘s in those moments of existential dread that we learn who we really are. That‘s why I like reading (and reviewing) books, and also why those topics are an undertone in my own writings. I do hope you enjoy these 5 books as much as I have.

Stefan's book list on apocalypse being dark times, but it‘s not the end (and might be fun, too)

Stefan Bogdanski Why Stefan loves this book

This was probably one of the most intense experiences with non-linear storytelling I ever had, and that did something to me I could not have predicted.

In fact, while reading this book, I started to turn the story into something of a philosophical discourse in my head. 

I really like how this book is at the same time utterly insane in parts—and I do say that with the greatest respect, it‘s the good kind of insane—while at the same time, it explores themes of dealing with earth-shattering events on a very individual level.

For me, the icing on the cake is that Kurt Vonnegut manages to even mix in a little history lesson there, because that bombing of the prisoners in Dresden? That did happen. And I didn‘t even learn about it in school—I learned it from this novel!

By Kurt Vonnegut ,

Why should I read it?

33 authors picked Slaughterhouse-Five as one of their favorite books, and they share why you should read it.

What is this book about?

A special fiftieth anniversary edition of Kurt Vonnegut’s masterpiece, “a desperate, painfully honest attempt to confront the monstrous crimes of the twentieth century” (Time), featuring a new introduction by Kevin Powers, author of the National Book Award finalist The Yellow Birds
 
Selected by the Modern Library as one of the 100 best novels of all time
 
Slaughterhouse-Five, an American classic, is one of the world’s great antiwar books. Centering on the infamous World War II firebombing of Dresden, the novel is the result of what Kurt Vonnegut described as a twenty-three-year struggle to write a book about what he had…

Book cover of The Chronocar: An Urban Adventure In Time

Seth Chambers Author Of Little Bird

From my list on time travel and the paradoxes that arise.

Why am I passionate about this?

I've been an avid reader of SF in general, and its sub-genre of time-travel, for most of my life, and have tackled this topic in my own writings as well. Time-travel tales often deal with inherent paradoxes, such as the Grandfather Paradox, which asks: If you go back in time and kill your grandfather, would you then never be born and therefore never commit the murder? If so, then your grandfather lives and you were born and . . . Such paradoxes boggle the mind and provide fascinating territory for SF authors to explore. 

Seth's book list on time travel and the paradoxes that arise

Seth Chambers Why Seth loves this book

This contemporary SF novel deals with a lot of the nitty-gritty, nuts-and-bolts aspect of time travel, as well as providing an intriguing story. So many time-travel stories gloss over many of the implications of this technology, but The Chronocar doesn't shy away from such concepts. It also features believable, rough-around-the-edges characters and a truly surprising plot twist. Also, one of my favorite things about this novel is how reminiscent it is of Golden Age SF.

Book cover of The End of Eternity

Stefan Vučak Author Of In the Shadow of Death

From my list on hard science fiction by old masters.

Why am I passionate about this?

I became hooked into science fiction as a kid the day I read an illustrated book of 20,000 Leagues Under the Sea. From then on, science fiction became an important part of my reading repertoire. Having wide-ranging interests, I enjoy military techno-thrillers, Anglo-French naval warfare, Greek/Egyptian/Roman mythology, most sciences, history of religions, with an occasional novel that strays from the norm and adds a sparkle to my reading. Mary Stewart’s The Crystal Cave and The Hollow Hills are very close to my heart. Just shows that I’m different. After all, I must do something when I am not writing my own novels! Although I have an extensive library of modern science fiction works, I am fond of many oldies.

Stefan's book list on hard science fiction by old masters

Stefan Vučak Why Stefan loves this book

Told by a master storyteller I enjoy reading, this book grabbed me immediately and drew me inexorably into the main character’s life as an eternity technician.

Not a unique theme – man manipulating his future – but I liked the twist when all future is threatened for the love of one woman. I kept turning pages, wanting to know how my hero would reconcile forbidden love at the price of eternity’s end.

This is a thoughtful book that denied me peace until it ended. I liked the technical concepts revealed in the story and how they were woven into very human reactions. A lesson for our modern time?

By Isaac Asimov ,

8 authors picked The End of Eternity as one of their favorite books, and they share why you should read it.

A spellbinding novel set in the universe of Isaac Asimov’s classic Galactic Empire series and Foundation series

Due to circumstances within our control . . . tomorrow will be canceled.

Book cover of 11/22/63

James Kinsley Author Of Parallels

From my list on scifi fantasy regular men doing amazing things.

Why am I passionate about this?

As a genre reader since childhood, I’m all-too-familiar with the tropes of the Chosen One, the Prophecy and all those things that lead the unsuspecting child of humble birth to fulfil their Great Destiny. I’ve no complaint against it, it’s been the source of many rich and inventive stories, but I find myself increasingly drawn to stories where the protagonist is an ordinary Joe (or Jo), sucked into uncommon events beyond their normal lives and forced to find a way to survive. It’s easy to grab attention with the threatened destruction of the galaxy. How much more satisfying, then, to make a reader care about the soul of one character.

James Kinsley Why James loves this book

For all the highly enjoyable shenanigans around using time travel to prevent JFK’s assassination, I came away loving this book for reasons I don’t normally associate with King–I genuinely loved his characters. Jake Epping is a sympathetic lead, and I became far more invested in his love for Sadie than in the assassination-thwarting.

I’d hesitate to say this is King’s finest book, but of those I’ve read, it’s definitely my favourite. I found the climax so emotionally satisfying; it genuinely moved me.

Book cover of The Accidental Time Machine

Don Kinney Author Of The Darkdrift

From my list on sci-fi for newbies, from a newbie sci-fi writer.

Why am I passionate about this?

I’ve been fascinated by science and space since I was a child and naturally gravitated toward science fiction. In many respects, it was a form of escapism, as I didn’t enjoy school. I always preferred escaping into another world or being taken on a journey to another world. It wasn’t until I got older that I realized that most great science fiction is a commentary on our own world and the issues we face daily. Science fiction, more than any other genre, does a better job of exploring and dissecting aspects of our world, which in turn helps us better understand our world and our relationship with it.

Don's book list on sci-fi for newbies, from a newbie sci-fi writer

The Accidental Time Machine is one of the few novels that I’ve read beginning to end in one sitting because I found it so interesting. This isn’t the type of novel that will change your life or change how you feel about something. It’s just good. A good, fun book that can be read in a couple of hours. Haldeman doesn’t waste any time getting the story going and from there he takes you on a ride more enjoyable than novels twice the length.

Book cover of The Door into Summer

Patrick G. Cox Author Of Captain James Heron First Into the Fray: Prequel to Harry Heron Into the Unknown of the Harry Heron Series

From my list on combining fantasy and social commentary.

Why am I passionate about this?

My great interests have been ships and space travel, and if one takes time to consider the similarities the parallels stand out. Ships, especially submarines, travel in a medium and through an environment that is hostile to human life. In space travel, the ‘ship’ becomes the only habitat in which we can survive for any extended period, leaving it without a space suit is a fatal move. I cannot claim to be an expert in closed environments, but it's a subject that has fascinated me throughout my life. Every ‘biosphere’ is unique and incredibly complex and depends on the symbiosis of an enormous number of living creatures right down to bacteria and even viruses. 

Patrick's book list on combining fantasy and social commentary

Patrick G. Cox Why Patrick loves this book

Heinlein created a fascinating story of an engineer double-crossed by his partner and his girlfriend. Like all Heinlein’s stories there are several twists in the tale along the way, a lot of wry humour, some well thought-out ‘science’, and the light relief is provided by the hero’s cat who accompanies him on a journey that involves cryogenics, time travel and ultimately a double-double cross that sees the hero come out on top.

I could have picked any of Heinlein’s books, they are all very well thought out, and all follow believable twists to the science of the day. In a sense his work is timeless and still very readable. The Door into Summer is one of the first of his books I read, and I was hooked.

Paul Levinson Author Of The Plot to Save Socrates

From my list on time travel that respect the paradoxes.

Why am I passionate about this?

I am an author of science fiction, as well as nonfiction, a singer/songwriter, and a Professor at Fordham University, and time travel has played a role in all of these endeavors.  I’ve written four novels and numerous stories which feature time travel, several songs (for example, “If I Traveled to the Past”), and talk about it in my classes.  The opportunity of going back in history and stopping a bad thing has always intrigued me, as has traveling to the future to see how things turn out. The paradoxes that can get in the way of that make thinking and writing and talking and singing about it even more fun.

Romance and love are of course great inducements to time travel, and have animated many a time travel novel and series. I like The Mindtraveler the best. It combines the struggle for true love with an astute knowledge of physics, a keen eye for the academic landscape, and a witty sense of humor.

And, of course, it would be glorious to get even with that mean-spirited, conceited, womanizing Caleb Winter. After years of experimentation in the back room of her lab, Margaret has finally built a time machine. The key, she discovered, is in teleporting not the body but the mind. And…


Book cover of Contagion

A.K. Caggiano Author Of Throne in the Dark

From my list on fantasy that makes you giggle and swoon.

Why am I passionate about this?

Every morning when I sit at my computer, I’m reminded by a post-it note stuck to my monitor that my self-ordained purpose is to “bring readers joy.” Like many, I escaped into books as a child, and I’ve been seeking out stories that encapsulate wonder, delight, and, most importantly, love ever since. I began my self-publishing journey in 2020 and am thrilled to have found my place in the fantasy romance genre, writing romcoms with a heaping spoonful of ridiculous magic. I’ve written a number of standalone novels as well as a (sub)urban fantasy series, Vacancy, and a traditional fantasy romance series with a satirical twist, Villains & Virtues.

A.K.'s book list on fantasy that makes you giggle and swoon

A.K. Caggiano Why A.K. loves this book

This book should perhaps be classified as sci-fi, but hear me out: the bulk of this novella follows two characters, one who is technically supernatural (we just happen to call him an alien), as they break out of captivity and quest through a forest. That’s fantasy enough for me, and the syrupy sweetness of these two can overcome any hesitation over on-page, spacey jargon.

I’ve never read a book that so wholly gets into the head of a non-human species as this, and it also had me cracking up the entire time. Simmi, the alien in question, is a germaphobe, to put it lightly, but his partner in escaping, Aurora, is patient and kind with him, and the love that blossoms between them is kick-your-feet delightful.

From my list on read after you binge-watch Bridgerton.

Why am I passionate about this?

I was born and raised in Mississippi, where ink and river mud run through our veins in equal measure. My parents were readers, and thus, I followed in their footsteps. Before long, I was reading their library choices and mine and still running out of books before it was time to visit again. From the moment I laid eyes on Elizabeth Peters’ Amelia Peabody series, I was hooked on historical mysteries. It took me forty years of life to realize I had stories of my own to share. I now live in Oxford, England, with my husband, two daughters, three cats, and lots of shadowy corners for inspiration.

Lynn Morrison Why Lynn loves this book

I am fairly convinced that Grace Burrowes is a time traveler, for I have never seen a modern author get period-specific language so right. Unlike all the other books on my list, the Lady Violet series does not include any murders.

Instead, Lady Violet’s penchant for solving “puzzles” made for a nice break from the more macabre. I got lost in the twisty details and adored the Agatha Christie-style reveal at the end of the book.

Jonathan Fortin Author Of Lilitu

From my list on epic Gothic adventure novels.

Why am I passionate about this?

As an autistic person, I was a deeply unhappy and anxious child, so naturally I grew up to be a goth, with scary stories becoming a way for me to manage my constant fear. The Gothic became one of my special interests, and something I’ve always enjoyed studying. Additionally, I’ve always loved imaginative, fantastical tales that helped me feel like I was escaping from the real world I hated (and honestly, still hate) so much. As a result, there’s a special place in my heart for books that combine the weird Gothic trappings I hold so dear with the action and magic of a fantastical adventure novel.

Jonathan's book list on epic Gothic adventure novels

Jonathan Fortin Why Jonathan loves this book

For me, Hyperion epitomizes the Gothic space opera.

It may not sound like it on the surface, with the book often being described as a sci-fi spin on the Canterbury Tales, but the devil’s in the details, and Hyperion has many details indeed, with each character’s story bringing us deeper into both their personal darkness and the darkness of the larger world: the labyrinthine Time Tombs; the Cruciform parasite that turns immortality into a curse; and of course, the eldritch godlike entity known as The Shrike.

As an easily-bored reader, I was floored by how easily Hyperion held my attention, as each of the characters’ stories not only made me care about them more, but also contributed to the adventure they shared...especially when it all came to a head in the sequel, Fall of Hyperion.

Spanning multiple worlds, time periods, and philosophical ideas, Hyperion has everything I want…
