3.5, 4 stars...I did enjoy this, the characters were strong and entertaining and I felt the connection between them and appreciated their dynamic. The sex was good. I will admit, and this is just an issue I have and therefore one of the reasons I don't read many sci-fi books, I get confused...a little lost...like my brain only works one way and I have a hard time envisioning parts of the story. I followed enough to understand what was happening, but there were aspects where I felt I was kinda like "huh?" Overall I enjoyed it and I see that Sophi's story is next and I'll probably pick that up.
