Poseidon's Prisoner
The third book in National Book Award finalist Katherine Marsh's fantastical series about a mythology-based boarding school finds Ava and her friends in the midst of a deep-sea battle for their lives. Perfect for fans of Percy Jackson and the TV series Wednesday!
It's a new school year, and Ava and Fia return to the Accademia on probation. Worse, their new headmaster is none other than Triton, Poseidon's domineering son, who transforms the campus into his own sea-themed domain.
As Fia struggles with her fear of water and the mystery behind her mother's suspicious death, Ava struggles to unlock the secrets of Fia’s lineage, including those of her ancestor Chimera.
With the help of their friends, a riddle from a Sphinx descendant, and the mythical Pegasus, Ava and Fia embark on a daring journey to Poseidon's golden palace to uncover the truth about Fia's mother. Along the way, they confront gods and reveal the real stories behind the so-called monsters. But Triton isn't forgiving, and it will take more than courage to right these ancient wrongs and escape with their lives.
Poseidon's Prisoner is the latest in Katherine Marsh's "unique and distinctly feminist fantasy series" (Publishers Weekly). The first book in the series is the award-winning Medusa, about which author and educator Colby Sharp said: "you won't be able to stop turning pages."
Katherine Marsh
Katherine Marsh has a gift for finding the heartbeat in history, the hidden corners, overlooked voices, and deeply human moments that echo into the present. Her stories, often set against sweeping backdrops of political unrest and social change, don’t just recount the past, they ask what it means to live through it, especially when you're young and searching for your place in a world that doesn't always make sense.
Before she was crafting award-winning novels, Marsh was steeped in stories of a different kind. As a journalist and editor, she learned how to chase truth through the noise, a skill that now gives her fiction its remarkable sense of urgency and clarity. Whether writing about a Syrian refugee hiding beneath the streets of Brussels in Nowhere Boy or exploring the trials of immigration and identity in The Lost Year, she doesn’t shy away from hard questions. Instead, she meets them head-on with empathy and grace.
The Myth of Monsters
In a Venetian boarding school where history’s shadows cling to every stone, legends are not just remembered, they are alive. At the Accademia del Forte, students carry the blood of creatures once branded as monsters in Greek myth. Their powers are unruly, their emotions dangerous, and their place in the world carefully controlled by gods who still demand obedience.
The Myth of Monsters consists of two books and series is set to expand with the upcoming release of two more books. The current recommended reading order for the series is provided below.
