Description


A suspenseful and stormy near-future tale with beach ghosts and singing sirens by the "marvelously entertaining" and "highly inventive" author JJ Fleming!

In a near-future world where hurricanes are weekly events, Eleanor escapes with her family to an abandoned beach town on Shadow Key after a storm destroys her school. There, she stumbles upon a strange and eerie discovery—a small colony of ghosts, each with their own peculiar story: a homesick pirate, a lovesick countess, the mysterious Nameless Mute Gentleman, and The Fabulous Singing Siren Sisters.

But the ghosts are in danger. Tentacled sea monsters called Oldies are stalking their souls, and with rising sea levels and more storms on the way, the ghosts’ time is running out. As a terrifying new storm approaches, Eleanor must rescue a ghost lost at sea and save her friends from the Oldies in a final, storm-chased battle of song against darkness. Wonders of Shadow Key is a quirky, suspenseful tale of one girl’s fight to use her voice for good.

Advance Praise

“A compelling page-turner… Authentic, witty, and full of the emotional complexities of a middle-schooler facing extraordinary circumstances…Wonders of Shadow Key encourages readers to look beyond the surface, embrace the unexpected, and find hope even in the most challenging times.”

The Children’s Book Review

Wonders of Shadow Key is the most delightful surreal semi-apocalyptic middle-grade novel you’ll read this year. Part Coraline, part Ray Bradbury, with a dash of Lovecraft, this book delivers just the right mix of spooky mystery and more subtle horrors—like family vacations, friends moving away, and online school. JJ Fleming serves up colorful ghosts and eldritch terrors with a lot of heart and a clever sense of humor.”

—Jude Atwood, author of Maybe There Are Witches

“Ghostly party-goers, a phantom pirate, and a cast of sassy spirits come to rely on perceptive Eleanor for help in Wonders of Shadow Key, a page-turning new book set in the Florida Keys of the not-too-distant future. Readers won’t be able to get enough of Eleanor and her new friends, and the mystery that will keep them guessing until the very end!”

—Chantel Acevedo, author of Muse Squad and The Curse on Spectacle Key

“An offbeat charmer of a dystopian ghost story—funny, touching, and surprisingly ripe for young readers living through climate change.”

—G. Neri, author of Tru & Nelle and Concrete Cowboy

“With its moody beach setting, a found family of ghosts, and a swimming pool that gave me the willies, Wonders of Shadow Key is a suspenseful and creepy story told with a lot of heart.”

—Jennifer Chambliss Bertman, New York Times bestselling author of the Book Scavenger series.

“I was immediately swept away by El’s adventurous spirit and the haunting mystery surrounding her new friends on Shadow Key. Fleming has crafted a gripping and enchanting story about friendship and our need to stay connected—to both our planet and each other—even and especially through life’s toughest storms.”

—Natalia Sylvester, author of Breathe and Count Back from Ten and Running

“In a near-future dystopian world where violent storms and floods have overtaken much of Florida, times are tough. Twelve-year-old Eleanor moves into an abandoned beachside apartment building with her parents to escape the ‘doorknockers’ who threaten their wobbly existence. Things heat up when she discovers they are not the only inhabitants of the building and El is the only person who knows it. When she discovers the truth about her new friends, open-hearted El fights to save them from terrible creatures who have come to claim them back into the dark waters of the gulf. A dancing pirate searching for his crew, a curmudgeonly countess hoping for romance, a faceless baby, and a stranger lost at sea are some of the odd characters conjured up by JJ Fleming, whose prose will make young readers think, laugh, and scream all on the same page.”

—Sue Lloyd-Davies, author of Pinkie’s Turnabout

“A delightfully warm story of friendship and trust.”

—Phillippe Diederich, author of Lalo Lespérance Never Forgot

It's kind of like if Coraline went to the beach...


It's only been five minutes and I already want to go back to Shadow Key!

Endless thank yous to J.J. Fleming, Victory Editing & NetGalley for allowing me the privilege of reading this book 💕

During an impromptu holiday* (*actually on the run from the Doorknockers), El finds herself on a creepy, crab infested, seaweed soaked* (THE SMELL!) beach with not an awful lot to do. After a quick conversation with Mrs Grapefruit Head, whom El assumes to be the village crazy lady*, (she wasn't far off) things take quite the turn.

El is welcomed with open arms into a patchwork quilt of a friend group full of marvellous and mysterious characters who may be vastly different in personality, but all have the same fear. The Oldies.

Will El be able to help her new friends to defeat The Oldies and live in safety, while also not tipping her parents off to what she's up to? Will the seaweed ever stop stinking? Will El see the baby better if she squints?

There's only one way to find out!

For your viewing pleasure, some of my favourite quotes from the book, COMPLETELY out of context 😊


"abandon hope all ye who enter here"

"Hon, no one ever called me normal my whole life."

"It's like a party on your neck!"

"KkkkkCCCCCChhhhhhcccccc!"

"lighthouses are a beacon of boredom for all"

And, my personal favourite:

"some angry child with dog-teeth."

Thank you again for this incredibly well written book. I'm not ashamed to say I shed a tear when it was time to leave Shadow Key, but I will be back many many times, just to check in with Mrs Grapefruit Head, The Captain, The Countess, The Siren Sisters and the rest of the gang. 💕

This was such a cool idea and I enjoyed the overall journey in this book, it uses the near-future element and how good the supernatural element was in this. I was hooked from the first page and enjoyed getting into this world and characters. I loved the world-building of this book and figuring out what was going on in this. The characters were so well written and cared about what was happening and glad I got to read this. JJ Fleming wrote this well and left me wanting to read more from them.

Wonders of Shadow Key is a fast-paced middle grade adventure that blends mystery, friendship, and just enough magic to keep young readers turning the pages. Fans of Small Spaces by Katherine Arden who prefer a less intense scare will find this a perfect pick.

At its heart, this is a story about climate change and loneliness. The author draws clear inspiration from the COVID era. Particularly, the way fear and safety measures created distance between people. That emotional undercurrent gives the story surprising depth. Beneath the adventure and supernatural elements lies a quiet reflection on isolation, misunderstanding, and the longing for connection. It’s also a story about friendship, an unconventional one, perhaps, but a powerful reminder that bonds can form in unexpected places.

Eleanor stands out as a brave and fiercely loyal protagonist. Her determination to help the ghosts and protect them from the Oldies shows both courage and compassion. She isn’t fearless, but she acts despite her fear, which makes her easy to root for.

There’s also a strong Cthulhu-mythos vibe running through the book almost like Lovecraft for children. The monster feels as though it could have slipped straight out of one of Lovecraft’s stories, yet it’s shaped in a way that suits a middle grade audience: unsettling, mysterious, but not overwhelming.

Overall, Wonders of Shadow Key is an engaging, imaginative read that will appeal to fans of adventure-driven middle grade stories with a touch of magic and suspense.
