THE FINAL BOOK IN THE NEW YORK TIMES BESTSELLING SERIES BY "ONE OF THE BEST URBAN FANTASY AUTHORS IN PRINT TODAY."--Darque Reviews

New York Times bestselling author Keri Arthur brings her Dark Angels series to a breathtaking conclusion as half-werewolf, half-Aedh Risa Jones treads a knife's edge between the salvation of the human race and its total annihilation.

The search for the last key to the gates of hell has begun, and half-werewolf, half-Aedh Risa Jones is in more danger than ever--and one misstep could prove ruinous. It's only a matter of time before Madeleine Hunter, the dangerous head of the vampire council, begins her hunt for complete domination. And for Risa, that comes with an alarming ultimatum: hand over the last key to Hunter or, one by one, her loved ones will die.

Now, it's a race against time for Risa to save those she loves, and to stop Hunter's apocalyptic plan to open the very gates of hell.
