"You won’t be able to stop turning pages . . . it is so stinking good!” —Colby Sharp, author of The Creativity Project: An Awesometastic Story Collection

From National Book Award finalist Katherine Marsh: Percy Jackson meets Wednesday Addams in this fantastical adventure about Ava, who attends a boarding school for the descendants of Greek monsters and uncovers a terrible secret that could change the world forever.

Ava Baldwin has always tried to keep her anger in check, just like her mom taught her. But when know-it-all classmate Owen King tries to speak over her yet again, Ava explodes . . . and Owen freezes, becoming totally unresponsive.

Although Owen recovers, Ava's parents whisk her off to her mother’s alma mater, the Accademia del Forte, a mysterious international boarding school in Venice. There, Ava and her brother, Jax, discover that the Olympian gods founded the Accademia to teach the descendants of mythological monsters how to control their emotions and their powers and become functioning, well-adjusted members of society.

But not everything at the Accademia is as it seems. After her friend Fia is almost expelled for challenging a teacher, Ava realizes the school is hiding a dangerous secret. To uncover the truth, Ava and her new friends embark on an adventure that could change the way they view history, mythology—and themselves—forever…or end their lives. 

Praise for Medusa

• "I'm in love with this book. Like the best Pixar movies, Katherine Marsh's Medusa is full of layers." —Jennifer La Garde, The Adventures of Library Girl!
• "Here is a novel that casts young people as agents of that change, while acknowledging the risks they face when adults, or a pack of patriarchal gods, lie in wait to silence those who speak truth to power. In this feminist retelling, girls take the lead while boys support and trust them." —The New York Times
• "Sound the sirens! Katherine Marsh has gifted us with the Greek mythology series we didn't know we were missing!" —Melissa LaSalle, The Book Mommy and What to Read to Your Kids
