This book started out strong but for me, it kind of finished weak. And it finishes with a cliffhanger, so if you want to know "what happens" you have to buy the next book.
I really enjoyed the flashback to when the couple was in college. It was believable and I could picture it all clearly. However...things just moved a bit too quickly for me for it to be believable. This held me back from four stars.
Our heroine though - she is a bad ass, and I love how she doesn't take shit. That is a big plus that I enjoyed.
