This book ultimately fell a little flat for me in the relationship department. The action was good, it was angsty in just the right amount and I liked both MC's enough, but their relationship never really ignited for me. The hot/cold aspect of Logan's feelings for Zak became annoying to the point where I wanted Zak to just be done with him. After a while, when the book should have been picking up for me, I found myself struggling to finish. Not a bad book, but just OK.
