This is really more of a 4.5. This has been my favorite of the series by far. I love Leo... I love Katharine... I loved how Leo got under her skin, and at times I wanted to smack Katharine for resisting him. But at the same time, I understood why she was resisting him. I thought it was a great love story, and the ending was very suspenseful. I mean, you know things will work out, but how they will work out is always in question.
