First 50-60% 5 big fat stars.
Second half: 3 stars.
Final rating: 4 stars.
I was really loving this up until just after the half way point and then it seemed to lose its momentum. It didn't have that same sexiness/naughtiness to it as the first half with the tension ratcheting up between Jo and Cam, which I was loving btw.
Nevertheless I did enjoy the story and look forward to reading more of this series, and just more books by the author in general.
