It’s been three months since demigod duo Nico di Angelo and Will Solace returned from Tartarus, and they haven’t had a single quest to tackle. So when Nico’s half-sister Hazel invites them to Camp Jupiter to handle a mysterious “issue,” Nico eagerly leaps at the chance for action. What Hazel didn’t mention is that she’s sheltering a group of monsters who escaped the Underworld! During Nico and Will’s journey, they showed these monsters they don’t have to be bad—there are choices. But when monsters start vanishing from camp, a dark power is at play, and Nico, Will, and Hazel realize they’re all tied to it...
