An incubus, a doppelganger and two Reapers walk into a temple. There's no punch line.

McKenna hasn't come this far, lived through all she's had to endure, to be brought down by Empusa's minions and her feelings for an incubus. When Marcus flashes his wicked eyes at her, it stirs up memories the Reaper would rather forget - but it also stirs emotions she thought were long dead. And behind it all, she and her makeshift family are now in a race against time for the souls of every human as Empusa joins forces with Anubis. 

Marcus is outwardly confident, inwardly shy and reluctant to reveal himself. For an incubus, he's surprisingly secretive, and his life revolves around protecting his sister and keeping them both safe - until he meets McKenna. Sweet, kind and fiery on the inside, he's instantly smitten by the Reaper who is just as protective of her family as he is of his. But can he break through the barriers she has set up to keep herself safe from the past?

And will anyone still be around to tell the tale when the battle is over?
