The second book in National Book Award finalist Katherine Marsh's Myth of Monsters series finds Ava and her friends up against their least-expected foe yet.

Ava Baldwin is ready for her second year at the Accademia del Forte. Now that she knows that her fellow classmates, descendants of the so-called Greek monsters, have been lied to by the Olympians, she's ready to help them uncover their ancestors' true stories-if only she can stay out of the way of the new headmaster, Perseus.

But laying low is easier said than done, especially when Perseus seems intent on trolling Ava, making it impossible to control her anger.

When Perseus banishes one of her friends, Ava must lead a rescue party on a whirlwind adventure from the Stygian Marsh of the underworld to the ice caves of Mount Etna with Ares and the spirits of violent death in hot pursuit. But the gods won't be tricked so easily this time . . .

• Medusa's Daughter: Ava Baldwin isn't a monster-she's a goddess. But she'll need to master her Gorgon powers to survive a school year designed to make her fail.
• A Feminist Mythology Retelling: The history books were written by the victors. Ava and her friends are determined to uncover the true stories of their ancestors, no matter how much trouble they get in with the Olympians.
• Friendship and Adventure: When the cruel new headmaster banishes one of their own, it's up to Ava's crew to stage a daring rescue from the depths of the underworld.
• Greek Gods and Goddesses: From a trolling Perseus to a vengeful Ares in hot pursuit, the biggest names in Olympus are stacking the odds against Ava.
