Love hurts, and no one knows it better than Georgina Kincaid. If she so much as kisses Seth Mortensen, the shy, sexy writer she's been dating, she'll drain his life force. Admittedly, the shapeshifting and immortality perks of a succubus are terrific, but it's completely unfair that a she-demon whose purpose is seduction can't get down with the one mortal who accepts her for who she is.

It's not just her personal life that's in chaos. Doug, Georgina's co-worker at a local bookstore, has been exhibiting bizarre behavior, and Georgina suspects something far more demonic than double espressos. She could use an assist from Bastien, an irresistibly charming incubus and her best immortal friend, but he's giving Georgina some highly distracting come-hither vibes. Georgina is going to have to work solo on this one - and fast, because soon, Doug's life won't be the only one on the line.

Indy Savage, cop's daughter, rock chick and used bookstore owner, has been in love with Lee Nightingale, once bad boy, now the man behind Nightingale Investigations, since she was five years old. No matter what ingenious schemes Indy used to capture his attention, Lee never showed an interest and Indy finally gave up. Now Indy's employee, Rosie, has lost a bag of diamonds and bad guys are shooting at him. When Indy gets involved, Lee is forced to help. Complicating matters, Lee has decided he's interested, Indy's decided she's not. But she can't seem to keep Lee out of her life when she's repeatedly stun gunned, kidnapped and there are car bombs exploding (not to mention she's finding dead bodies).

Indy's best bet is to solve the mystery of the diamonds before Lee. Lee's challenge is to keep Indy alive and, at the same time, win back her heart.
