3.5-4 stars. 
 to be fair, it was a really good book. but with the exception of Lucas' book, I've always found it hard to focus when a story is mostly about the cats. I'm not as interested in their dynamics, so I'm not as invested in the characters. 
 I liked it and I liked Dorian. He's one of the more flawed characters in this series, and I enjoyed him a lot. He is my second favorite cat after Nate. I liked watching him work through his prejudice to embrace Ashaya. The side-mystery (the whole Omega project and Amara) was one of the more interesting ones - it held my attention. Ashaya was cute. 
 Good story. 
 Oh yes, the last 10% of the book was probably my favorite.
