Book cover of Mrs. Frisby and the Rats of NIMH

M.R. Fournet Author Of Brick Dust and Bones

From my list on giving kids beautiful nightmares.

Why am I passionate about this?

As a middle grade horror writer, I attribute my love of everything spooky to my early obsession with reading. Of course, my little brain was twisted already, but I found a perfect home in the monsters and ghouls of the library. These are the five books that inspired me to become a writer who scares children in the best possible way.

M.R.'s book list on giving kids beautiful nightmares

M.R. Fournet Why M.R. loves this book

Another Newberry Medal winner, this book is unlike the rest because the terror doesn’t come from the supernatural. It’s from the cruelty of mankind and scientific testing on animals.

What I love about this book, and the movie made in the “nineteen hundreds”, is it respected the readers. It told us a frightening story and trusted us to be able to process it. Like all the books on this list, the authors didn’t treat us like kids. They treated us like readers, and that’s the best thing a writer can do for their fans.

Book cover of Animosity

Robert Repino Author Of Morte

From my list on animals becoming sentient.

Why am I passionate about this?

In addition to writing novels, I’m a humanities editor for Oxford University Press. So, I’m interested in the political and theological implications of non-human intelligence. I wonder how people would react to such a revelation. Some would be fascinated by this radical new perspective. Others would be horrified at what they perceive as a transgression against nature. I’m also drawn to this topic because I still vividly recall the entertainment of my youth, which regularly featured anthropomorphic animals. Sometimes they’re just cool or funny. But on occasion—like with The Secret of NIMH—they raise profound questions of identity and rebellion, even for an audience that is too young to understand.

Robert's book list on animals becoming sentient

Robert Repino Why Robert loves this book

The animals in Bennett’s graphic novel do not gain sentience gradually, nor is their experience hidden from the rest of the world. Instead, animals all over the globe one day “wake up” and begin to wage war on humanity, and each other, creating a state of upheaval that few can comprehend. It’s that boldness and sheer shock value that I found most appealing. Like all good stories about animals gaining sentience, this one toys with the idea that non-human intelligence is some sort of affront to the natural order. At the same time, the story is grounded in the love between 11-year-old Jesse and her dog Sandor, who has sworn to protect her on a perilous journey. I enjoyed bouncing back and forth between affection and horror. Maintaining that balance is no easy feat!

Robert Repino Why Robert loves this book

A childless couple adopts a chimpanzee named Looee, and you already know from reading that sentence that it will lead to trouble and heartbreak. After a few pages, I didn’t care. In McAdam’s skilled hands, the inevitable sadness doesn’t matter, because the delicately handled point of view perfectly captures a doomed creature trapped between two opposing identities. In contrast, we also meet Podo, an alpha chimp at a research facility seeking to test the intelligence of primates. Podo is fully ape, but he is turning into something more. Their paths soon join, taking them deeper into a gray area between human and animal that I had never seen rendered on the page so vividly before.

So one day he brings home Looee - a baby chimpanzee. Looee, exuberant and demanding, immediately fills the gap in Walt and Judy's life, and they come to love him as their own son. Like any child, Looee is affectionate and quick to learn, generous and engaging. But he is also a deeply unpredictable animal, and one night their unique family life is changed forever.

Robert's book list on animals becoming sentient

Robert Repino Why Robert loves this book

Though there is a supernatural element to this story, it features a dog named Tomorrow who learns about the real world in the most mundane way possible: by hanging around too long, and experiencing the inevitable loss that we all face. After his master injects Tomorrow with an immortality elixir, the two are separated, and the dog waits over a century for his companion to return. Along the way, he witnesses historical events, while meeting animals who live the innocent life he once enjoyed. By the time Tomorrow resumes his search, he is a changed dog, a person in every sense of the word, though his identity remains rooted in loyalty and love. This book makes you wonder: can you hold onto those good things after life has chipped away at you for so long?

Book cover of Ka: Dar Oakley in the Ruin of Ymr

Emma Marris Author Of Wild Souls: Freedom and Flourishing in the Non-Human World

From my list on what it is like to be a wild animal.

Why am I passionate about this?

I have written about the environment as a journalist since 2005, for magazines and newspapers including National Geographic, The New York Times, and Outside. For my last book, I wanted to write about animals as individuals—not just as units in a species, the way they are often thought of by conservationists. Diving into research about animal selfhood was an amazing journey. It helped shape my book, but it also changed the way I see the world around me—and who and what I think of as “people”!

Emma Marris Why Emma loves this book

I don’t read very much fiction (although I want to read more!) but I thought it would be interesting to check out some novels where animals are main characters.

I read several, and this is the one I still think about all the time. The main character is a crow and although the book is a fantastical mytho-poetic adventure through time and space, it is also a wonderful exercise in cross-species empathy.

While you are reading, you really feel like you understand what it means to be a crow. It really stuck with me; I found it really rich and wondrous.

KJ Kabza Author Of The Ramshead Algorithm: And Other Stories

From my list on starring sentient animals (that not enough people know).

Why am I passionate about this?

Being a human is fraught, so I've always been fascinated by stories of sentient animals, long before I sold my first short story at age 19 (about a tiny dragon that lived in a bathtub drain) or my 48th story (which features talking sand cats and is reprinted in my collection The Ramshead Algorithm: And Other Stories). While most of my 90+ published stories star humans, talking animals are a reoccurring motif in my work and in the ????+ books I've read across 40+ years. If you're ready to branch out beyond Watership Down and Redwall, here are 5 books that more fans of sentient animals should know about.

KJ's book list on starring sentient animals (that not enough people know)

KJ Kabza Why KJ loves this book

Zucchini the ferret, born in the Bronx Zoo, leads a bleak life.

When he learns about the outside world, he yearns to escape—but when he does, it's straight into chaos.

I read Zucchini many times as a child and last read it in my 30s, and it's wonderfully more grimdark than I remember. Published in 1982, the book is 1980's-New-York gritty, and so are the hard adult lessons: fighting for your needs is full of risk; betrayal is common; love, compassion, and understanding are scarce; and idealism has an unsustainable cost.

But this makes the bits of joy that Zucchini wrests from the world all the more vivid. The story, like the world, is hard; but the story, like the world, has hope.

KJ Kabza Why KJ loves this book

In Paul Galico's The Abandoned (copyright 1950), 8-year-old Peter is transformed into a kitten after a mysterious accident, befriends an older stray, and learns how to behave as a cat as he teaches his new friend about the occasional goodness in people.

I grew up with cats and was obsessed with all things feline, and I couldn't resist this story, in its charmingly British voice, that explained to the reader how to properly behave as one; nor, I imagine, could many other younger cat lovers if they knew about this book.

(Because it if happened to Peter, maybe it could happen to us, and we ought to read this how-to, to be prepared. You know… just in case.)

KJ Kabza Why KJ loves this book

Tom Shachtman's Beachmaster, in which the sea lion Daniel Au Fond becomes obsessed with deciphering the fragments of an ancient legend—or is it a key but semi-forgotten piece of sea lion oral history?—hit my young world in the midst of my own obsession with "The Cryptic Prophecy" fantasy trope.

Marine mammals are an uncommon choice for sentient animals in fantasy, and all this plus my own permanent obsession with exploration meant that the vast, literally ocean-crossing scale of this story, with its multiple and differing sentient animal cultures, made it irresistible.

Luckily for me, Beachmaster is actually the first book of a trilogy (followed by Wavebender and Driftwhistler), so this was only the beginning. (Consider this paragraph a vote for all 3.)

Benjamin L. Carp Author Of The Great New York Fire of 1776: A Lost Story of the American Revolution

From my list on books that get beyond the “bedtime story” of the American Revolution.

Why am I passionate about this?

I like thinking about the people who misbehaved in the 1700s. As a teenager, I was initially drawn to journalism as a medium for telling stories, but in college, I was entranced by the stories I could tell with early American sources. Years ago, Jan Lewis noted that many readers want “bedtime stories” about how great the American Revolution was, but there’s much more to the Revolution’s history. Now, I’m a history professor at Brooklyn College and the Graduate Center of the City of New York. Having lived in the Boston area and New York City, it’s been a thrill to write books about the American Revolution in both places.

Benjamin L. Carp Why Benjamin loves this book

I went into this book cold, knowing nothing about it beforehand, and it left a powerful, thrilling impression. I almost don’t want to say anything else about it so that other readers can experience the same suspense.

Readers might know Anderson from Feed or his other quirky genre-bending books. This book, the first of two volumes, is a work of historical fiction set mostly in Boston. It uses eighteenth-century language to tell an epic tale about the American Revolution, the Enlightenment, and the dark side of both.

It’s a book of horror (perhaps even anticipating the movie Get Out), with intricate details that will delight a certain kind of reader.

But when their thesis moves from the academic to the experimental, things go horribly wrong. They become EOs, ExtraOrdinaries, leaving a body in their wake and turning on each other.
