Middle Grade Sci-Fi Mystery

The X-Files meets Scooby-Doo in THE THIRTEENTH CIRCLE, a middle-grade mystery from MarcyKate Connolly and Kathryn Holmes, featuring two unexpected friends, crop circles, science fairs, and Men in Black, perfect for both the highly scientific and cryptid enthusiasts alike.

Cat knows aliens are real, and she’s determined to prove it. By studying the Weston Farm Circles, her town’s legendary crop circle phenomenon, she’ll not only demonstrate the existence of extraterrestrial life, but also win the grand prize in the McMurray Youth Science Competition―a feat she’s sure will impress her distant NASA scientist father.

Dani most certainly does not believe in aliens. How can she, when they go against every scientific principle she’s been taught? So when Dani is paired with Cat to enter the McMurray Youth Science Competition―which she has to win to avoid going to her parents’ artsy summer camp―she knows she’s at a disadvantage. Her solution? Disprove Cat’s theory, of course . . . without telling her partner her true intentions.

But as the girls bond over science, it becomes clear that there is something strange about the Weston Farm Circles. And when Dani and Cat’s project is threatened by suspicious forces, they’ll have to work together to expose the truth, once and for all.

Brimming with danger and magic, this new fantasy adventure from acclaimed author MarcyKate Connolly will leave readers breathless as Aria discovers the strength of her courage―and the power of friendship.

Aria grew up in a castle, among the clouds with creatures of the air. She spends her days racing and soaring through the sky with her best friend, Gwyn, a young gryphling. At night, she falls asleep to the music of the Wind. 

One day, the Wind vanishes, taking all Aria holds dear with it. Aria and Gwyn go on a desperate search, only to discover the Wind has been kidnapped by a sinister alchemist named Worton. 

Nothing will keep Aria from rescuing the element who raised her― not a riddle, not a quest, not a race against time. Except Worton can’t be trusted, and the Wind is not the only one in grave danger…

Young Adult Fantasy

Aissa’s life is a web of carefully constructed lies. She and her twin sister, Zandria, are Magi spies, a magical people most believe to be extinct. And they’re on a mission for revenge.

This action & adventure spy thriller—a fantasy spin on Romeo and Juliet from New York Times bestselling author MarcyKate Connolly—is perfect for fans of Marissa Meyer and Elly Blake and is about to become your new obsession!

By day, Aissa and Zandria play the role of normal young Technocrats eager to fulfill the duties of their new apprenticeships. By night, they plot their revenge to retake their city from the Technocrats. But then Aissa is given a new mission: find the heir to the Technocrat throne, who is rumored to be one of the Heartless, and kidnap her. Born without a working heart, the Heartless survive with a mechanical replacement.

Aissa is more likely to be caught than to be successful, but she’s never been one to turn down an assignment, even if the hunt is complicated by a kind Technocrat researcher who is determined to find a cure for the Heartless. But when Zandria is captured by the Technocrats, Aissa will do anything to get her sister back. Even if it means abandoning all other loyalties—and missions—and deciding whether or not it’s worth risking everything on getting help from her sworn enemies.

Now torn between two worlds, Aissa must decide who she can trust. Especially when it comes to her twin.

Now without a home and on the run, Aissa has never felt so trapped and alone even with her sister and friend by her side. Zandria—once her other half—has become cold and inflexible after her time in the Technocrat’s dungeon and is bent on revenge Aissa no longer feels. Their friend Remy may still side with his father, a Magi leader who refuses to believe his spymaster has turned traitor. And Aissa herself is now an enemy of her Magi people after falling in love with—and binding her heart to—Aro, a Techno prince who puts all their lives at stake.

Using clues her parents and others left behind, Aissa is determined to uncover the secrets of the Alchemist Alliance that created her and Zandria’s unique magical powers … as well as learn whether the Alliance’s research holds the key to healing the rift between the Magi and Technocrats after centuries of war. But with her people preparing for battle, and Darian poised to use the Technocrats’ might for his own ends, it will take more than lost spells and hidden secrets to accomplish her goal. Especially as the dangerous bond between her and Aro grows deeper and threatens everything Aissa has ever believed.

“A taut, emotionally arresting fantasy.”

Middle Grade Fantasy

Neil Gaiman meets How to Train Your Dragon in this beautifully illustrated middle-grade novel about a boy, his trusted dog, and his best friend, as they race to save the stars before their light is extinguished for good.

When the world first formed, the night was black and filled with dark creatures. The Elders knew their people couldn’t survive under such a threat. So they gave their hearts to the sky in the form of stars to keep evil away.

Now, eleven-year-old Kyro is a Star Shepherd like his father. He’s spent his life tucked away in the small town of Drenn. There, the family watches the night sky for falling stars―and rushes to rescue them when they do.

When too many stars start falling at once, and disappearing before they can be saved, Kyro’s father journeys to report the threat. But when he doesn’t return, Kyro, with the help of his best friend, Andra, and his trusty dog, Cypher, must find a way to save the stars before the dark creatures make a terrifying return.

Emmeline has grown up with a gift. Since the time she was a baby she has been able to control shadows. And her only friend and companion is her own shadow, Dar.

Disaster strikes when a noble family visits their home and offers to take Emmeline away and cure her of magic. Desperate not to lose her shadows, she turns to Dar who proposes a deal: Dar will change the noble’s mind, if Emmeline will help her become flesh as she once was. Emmeline agrees but the next morning the man in charge is in a coma and all that the witness saw was a long shadow with no one nearby to cast it. Scared to face punishment, Emmeline and Dar run away.

With the noble’s guards on her trail, Emmeline’s only hope of clearing her name is to escape capture and perform the ritual that will set Dar free. But Emmeline’s not sure she can trust Dar anymore, and it’s hard to keep secrets from someone who can never leave your side.

Then one night the Cerelia Comet-the reason for their magical abilities-returns… Twelve years too early. The return of the comet can only mean one thing, Lady Aisling has a sky shaker under her control and is hoping for a new batch of talented children to add to her collection.

“This book contains plenty of action and intrigue to keep the reader turning pages. It is quick to read and contains enough unsolved mysteries to make the reader look forward to the next title in the series.”

“The interplay of light and dark and the moral ambiguity threaded through Connolly’s worldbuilding are everything readers have come to expect from the author of Monstrous (2015)… Fans of Serafina and the Black Cloak (2015) will find much the same chills and sequel-primed mystery here.”

The city of Bryre suffers under the magic of an evil wizard. Because of his curse, girls sicken and disappear without a trace, and Bryre’s inhabitants live in fear. No one is allowed outside after dark.

Yet night is the only time that Kymera can enter this dangerous city, for she must not be seen by humans. Her father says they would not understand her wings, the bolts in her neck, or her spiky tail—they would kill her. They would not understand that she was created for a purpose: to rescue the girls of Bryre.

Despite her caution, a boy named Ren sees Kym and begins to leave a perfect red rose for her every evening. As they become friends, Kym learns that Ren knows about the missing girls, the wizard, and the evil magic that haunts Bryre.

And what he knows will change Kym’s life.

Reminiscent of Frankenstein and the tales of the Brothers Grimm, this debut novel by MarcyKate Connolly stands out as a compelling, original story that has the feel of a classic.

A witch has come to the city of Bryre. She travels in a hut that has chicken feet, and is ravenous for children. And once she gets what she desires, she never lets it go.

But when the witch captures Hans, Greta’s little brother, Greta refuses to let her have him. The two strike up a bargain. Greta will retrieve something the witch desires in exchange for her brother’s freedom.

To get the prize Greta must travel to Belladoma—a city where she was once held captive—which brings back terrible memories. With the help of a new friend, Dalen, a magical half-boy and half-horse, Greta embarks on the journey and tries to overcome both foes and her own weaknesses.

For fans of Monstrous and new readers alike comes the story of an epic quest and a heroine who will stop at nothing to save the one she loves most.


“A likely read-aloud that has its share of guts, blood, and grim reality within this fantasy land, Monstrous will keep young readers thinking about trust, good and evil, friendship and loyalty, and devotion to community.”

“Like a literary mad scientist, MarcyKate Connolly takes bits from classic fairy tales and legends and uses them to assemble a creation that is wholly original and wonderfully strange. Subversive, bewitching, and whip-smart, Monstrous is a marvel of storytelling alchemy.”
          -Anne Ursu, author of Breadcrumbs and The Real Boy

“Pays tribute to classic fairy tales while turning the tradition on its head. A smart, ambitious adventure, led by a heroine whose differences only enhance her humanity.”
          -Emma Trevayne, author of Flights and Chimes and Mysterious Times

“Readers seeking a lengthy, thoughtful novel, particularly those who appreciate careful world-building, will find this worth their time.”
          -Bulletin of the Center for Children’s Books

“Once I started reading, I could hardly do anything else–the elegant writing, vividly imagined world, and Kymera’s marvelous strength kept me hooked. Brave, refreshing, and entirely enchanting, Monstrous is a book that will stand the tests of time.”
          -Claire Legrand, author of The Cavendish Home for Boys and Girls and The Year of Shadows

“Frankenstein meets Coraline in this creepy tale. Kymera, reborn of animal parts and a human brain, knows nothing except that she loves her father, who has built her for a mysterious, disturbing purpose. Though Kymera’s guileless narration ensures that readers always suspect more than she does, Connolly’s technique effectively builds a sense of dread, as does her skillful interweaving of fairy-tale elements.”
          -Horn Book Guide

“From its first line, Monstrous had me in its grip. MarcyKate Connolly has created a fresh and wildly inventive dark fairy tale about Kym, a protagonist as sweet as she is strong. Kym’s bravery shines, as she fights against the menacing forces in Bryre and also struggles to figure out where she, a self-described monster of a girl, belongs. This remarkable, absorbing debut will enchant readers.”
          -Rebecca Behrens, author of When Audrey Met Alice

“Connolly invokes fairy-tale elements with ease, and…the formidable theme of sacrifice resonates far beyond the final page.”
          -Publishers Weekly

“Magic, fantastic creatures, mythology, & a bit of Mary Shelley’s Frankenstein combine here for an exciting…tale.”
          -School Library Journal

“While Kymera’s journey reads like a timeless fairy tale, my favorite thing about her is that she’s not waiting to be rescued. She is the rescuer. She’s tough, vibrant, intelligent and brave enough to be vulnerable. This is a dazzling and unique once-upon-a-time about a girl who is part dragon, part bird, part cat, all hero.”
          -Natalie Lloyd, author of A Snicker of Magic


“Fans of the first installment will seek out this adventure-filled fairy tale.”
          -School Library Journal

“A fantastical adventure fortified by its flawed heroine.”

“With vials of potions, clues in a book of fairy tales, and a hungry sea monster, there is magic to behold on these fast-paced pages. Within this creative realm, Connolly compassionately explores human emotions as Greta grapples with a newly discovered lineage. A welcome return to a complex land of fantasy and friendship.”

“It’s nice that Greta’s sort of a mess—she flares up at the wrong times, she alienates would-be allies on occasion, and she’s just plain grumpy. Even with her flaws, her fierce dedication to her brother is admirable, and her slow transformation into a more accepting, open person is all the more satisfying given her earlier closed views.”
