4.5, but I'm rounding up because I swooned all over myself with this book. I've read a looo-hot of Jill's books, and while I love her books, they do have a certain formula to them. And though this one had a small glimpse of that (commitment phobes), it was a FRESH read. The UST was outta this world. Sam was unique, fun, ballsy, and not in a fake way. I truly loved her character. And Jack? He had me at 6'6". (ok, so he was way more than height, and truthfully would give Brady a run for his money in the swooniest Hero Jill's ever created). (also, what is it with her dumbest titled books being the best ones?!? See also: Animal Magnetism)This baby is going on the reread list.
