Krescent Dune is used to fighting monsters on her island, but she's unprepared for the monsters lurking in the deep in this new South Asian-inspired fantasy from the highly-acclaimed author of Monsters Born and Made

Krescent Dune is buried under the weight of her dead parents' debt and the ruinous legacy they left behind. The only way she can earn enough money to escape her unforgiving island is by fighting monstrous amphibians in underground fighting pits. She's never lost a match, until now.

Desperate, Krescent is offered a deal. Her debts will be erased if she joins a hunting party for a dangerous rescue mission deep beneath the island. With no other choice, Krescent is forced to play nice as the group's bodyguard, even though every step that brings them deeper underground means she must face the terrifying truth that she is trapped with her childhood enemy and people who would gladly kill her if they knew who her parents were.

As the group journeys down beyond where their maps end with creatures never seen before, Krescent begins to suspect there's more to their rescue mission than first meets the eye. Soon enough, they are abandoned in the deep dark underground, with only monsters seen and unseen for company.
