Run of Ruin by Nikki Robb

Survive the Trials. Defy the System. Protect What You Love.

Every year, the Collectives of Nexum send their elected representatives into the Reclamation Run, a brutal gauntlet of deadly trials where victory means food, medicine, and clean water for your people and failure means death. Brexlyn Hollis never wanted the title of Challenger, but when her little brother’s life hangs in the balance, she steps into the arena determined to win.
Inside the Run, nothing is as it seems. There’s Ezra, the criminal, Zephyr, the cold-eyed Praxis puppet, and other competitors like Thorne and Briar, each with their own reasons for risking everything.
But as the Trials turn darker and the true cost of the Reclamation Run is unveiled, Brexlyn discovers she’s more than just another pawn in Praxis’s game. There’s a storm building inside her, one they never saw coming.
