This is the 11th book in Lynsay Sands' Argeneau Vampire series. I read the first 10 and can't remember why I didn't read the last one, but it's been so long I'd forgotten how much I like these guys!
Let me start by explaining the vampire's history. They are descendents of Atlanteans, who did some kind of experimentation and ended up with an immune system that can heal almost all wounds and sicknesses, but it uses up their blood so they have to drink human blood to replenish their supply. They can go out in sunlight but their bodies use so much blood trying to repair the sun damage that in general they just don't go outside. Also, they can read and control minds, except in the case of their "life mate". In that case, it doesn't matter if their mate is human or vampire, they can't read them at all.
Decker Argeneau Pimsms is a vampire enforcer, sort of like vampire police. He's out with his partner, hunting down a rogue vampire who used to be an enforcer, when they come across two sisters, Dani and Stephanie McGill, being held captive by a whole group of rogue vampires. In the ensuing confusion, Decker manages to grab Dani, but one of the rogues escapes with her sister. They spend they spend the rest of the night trying to track down Stephanie and the rogue vampire with no success.
During this time Decker tries to control Dani's mind and realizes he can't. He's not too thrilled about that because he didn't make a good first impression and she doesn't seem to like him very much.
They hole up at a local safe house, and Dani learns a bit about the vampires, and starts falling for Decker. While out running errands, Dani is kidnapped by the same rogue that has her sister. He is a different kind of vampire, a fangless vampire, and 1 out of 3 fangless vampires goes crazy. This one is absolutely nuts. He has plans for Dani and her sister -he wants to impregnate them and create more vampires.
I'm not going to give a bunch of spoilers, but his plans are far-reaching and Dani (and her sister) goes through some difficult situations.
This book had lots of action and sexy time, and it was nice to see some of the characters from the previous books. If you've not read the series, I recommend you give it a try!
