Wicked Appetite by Janet Evanovich

Kicking off a new series, Evanovich sticks very close to the style that has served her so well in the Stephanie Plum stories. You could substitute Stephanie for Lizzie and come up with pretty much the same woman. A little klutzy, not quite comfortable in her own skin, but this one has a job. In fact, it's a pretty good job making cupcakes at a store in Salem, Massachusetts. Then, one day, two mysterious men show up. One (Gerwulf Grimoire) is described as your stereotypical vampire but he apparently has the power to generate heat through his hands. The other, Diesel, described as a super-tanned beach bum, makes Lizzie burn. 
She discovers that they are all "Unmentionables" with certain powers, hers is to locate things. In the current climate of an overwhelming number of paranormal talents and creatures, having someone be granted such an underwhelming talent was... odd but refreshing. Well, she also makes perfect cupcakes which, IMHO, is much better than being able to move things with your mind or whatever anyway.
Diesel needs her help to gather seven stones, each of which represents one of the seven deadly sins, together, a person could rule the world.
Fast-paced, quirky and a fun read.
