Since I read all 3 parts, gathered I can rate the complete book. Even though the storyline and the character development were more of 3.5 stars, I did love our hero... and sex was sizzling hot, aptly constituting the category it was meant to fall under.
Part 1, 4.5 stars
Part 2, 3.5 stars
Part 3, 3.5 stars
You can find a complete review in the following.
