I really enjoyed this one. This was a very well written short book that felt longer than it actually was. Mainly because the author did a great job of making the reader feel the two protagonists fall in love. There was a depth to the relationship that you don't often get in books of this length.
I liked the convention of the flashbacks. They were well incorporated with the present day and did a good job of explaining the genesis of the relationship and where each of the two characters were coming from. I also liked that they were both appealing and realistically flawed. You liked them, and yet they both make mistakes. Also, he isn't some super alpha you see ad nauseum and she isn't an irritating -- which also sadly seems to be a staple in some IR romances.
The love scenes were sensual without being explicit.
