I really loved the beginning and end of this book and the whole association with romance novels. The writing was fun with lots of clever lines. Both MCs were very appealing and the sex scenes were hot.
There isn't much of a secondary plotline here, and the book is long (400 pages on my iPad). So it did feel like the middle was sort of unfocused -- just a whole lot of pages of sex scenes with the MCs getting more attached over time. Still, for the strengths of this book, I give it a 5.
