I really enjoyed this suspenseful romantic story. The plot was interesting with a lot going on but never confusing. I thought the suspense angle of this book was really good, and I enjoyed all of the undercover agent aspects. I liked both of the characters who were very troubled in their personal lives. It was a little difficult reading about Zak's drug and alcohol issues at the beginning, but I really liked him as a person. I really liked Logan's character. I loved the way he took care of his brother. The biggest reason this is not a five-star read for me was because of the constant back-and-forth denial of the relationship. I got it at first, because of their backgrounds. But by the end, I was just getting frustrated with it. Nothing kills the high like telling somebody "this can never happen again". The sex scenes were hot though!
