The lost city lies beyond a locked gateway. But the key is not what it seems... Now a map-maker extraordinaire, Finch must find the place Erebus so desperately seeks-although the "how" and "why" remain unclear. And a certain vengeful Necromancer is bent on beating Erebus to the punch, and he'd be more than happy to make Finch collateral damage. With his friends' lives on the line, Finch will fall back on his old trickster ways to get his hands on the gateway's key. In secret, he plans to uncover a loophole, a way to end his servitude for good. The answer might lie in Erebus's past servants and their storied history with the djinn... The djinn have lost their connection to Erebus, and Raffe doesn't know how much longer he can cope before his alter ego goes insane. That's the only reason he agrees to travel halfway across the world to find answers for Finch. Raffe aches to end the djinn curse that threatens his future with Santana, but he'd have to achieve the impossible: separate himself from the demon within.
