The Curse Keepers by Denise Grover Swank

I really, really, really enjoyed this book (like really) I can not stress how much I was into it. I bought the next one before I'd even finished reading it. Ellie Dare Lancaster works in a diner. A hottie comes in who she instantly knows is trouble. He is going to touch her and she knows by her breathing she shouldn't let him.
In short there is a curse. Not on Ellie. Each member of her family will know the curse. Her father passed it down to her. They are the curse keepers. There is another family who are the second. There are only two curse keepers. One from each family. When the two meet and touch the curse is lifted, the gates to hell open and with it and well work that out for yourself.....
