Kierce sacrificed himself to save Frankie, and now it’s her turn to rescue him. Whether he wants her to or not. That means venturing into Abaddon, the land of the dead, and hoping she can locate him within its shadowed depths before Dis Pater notices his favorite toy is missing. But Dis Pater isn’t the only deity she has to fear. Frankie’s father has learned of her journey down to his domain, and he won’t take no for an answer when he welcomes her into his home. As if one MIA parent materializing wasn’t bad enough, her mother arrives with her own emotional baggage in hand. Forget the perils of traversing the underworld. Navigating this family reunion just might be what kills her.
