Lost in Prophecy. The Ascension Series, #5

Elise Kavanagh is too busy liberating slaves in the City of Dis to worry about what's happening on Earth. She hasn't even noticed that more than three thousand people have gone missing-not until an anonymous client hires her organization, The Hunting Club, to rescue them. The man asking for help doesn't seem to exist. But the trail of clues is too strange to ignore, and she finds herself caught in the investigation. Werewolf Alpha Rylie Gresham is absorbed in troubles of her own.
The pack is disobeying her, and the cult camped out in Northgate seems to be the source of the problem. Her mate, Abel, has resolved to fix it one way or another-even if it means going over Rylie's head and killing their enemies. Through secrets, lies, and assassination attempts, Elise and Rylie find that they have a new enemy in common. And what it takes to prevail might mean shattering the universe.
