Temptation. Immortal Soulless, #5

Things have been far too quiet since Aviva foiled Viktor's plans to rise to power as high elder of Maelstrom. She's certain he won't give up so easily, but has no proof, no connections, and no hope of survival if she dares to stir up trouble again. Aviva's temporary peace is destroyed when an unfamiliar vampire attempts to assassinate her. She suspects Viktor is behind it, but there's no help for her among the clan's higher-ups; Miranda can't afford to get her hands dirty when Aviva herself is being investigated for murder.
As the situation spirals out of control Aviva instead seeks help from a strange group of vampires who exist at the very edges of clan society. It's hard to know whether she can trust them, and harder still to know what to make of the powerful being she meets among them who claims to be an angel-or possibly a demon. Aviva will have to choose her allies wisely if she wants to save herself and her clan from an enemy that's larger and more dangerous than she ever imagined.
