If the difference between "I really liked it" (4 stars) and "amazing" (5 stars) is that I re-read it, or in my case re-listened to it, then it deserves 5 stars. It is probably a 4 star book, due to the author going over and over the heroine's angst. 
 This is an alien / human female fall in love story, with hot but not dark sex. Why did I like the series? An emphasis on trust and a male character who could be dominant without being an a333ole. Plus, the alien's inventions are fun. 
 Warning: Don't read unless you've read the first two books in the series. While the author does a good job of recapping what has happened previously without boring series listeners, you just won't enjoy this volume without having read the prior two. 
 My disclaimer: I bought the book, I don't know the author or publisher, and I wasn't asked to review it.
