This was not one of my favorite Harper Fox books. There was something about the characters, and the plot that I found hard to connect to, and I felt like I never became invested in the story. It wasn't bad, but it felt like a bit too much of a summer blockbuster style plot with the military experiments, and such. I also had a hard time understanding Daniel's relationship with Jason. Jason didn't seem like a bad person, but a bit controlling, and overbearing. It almost seems like Daniel was swallowed up a bit. I don't think it was malicious just a little too paternal for my tastes. I like Rayne, but it seems like their relationship moved a bit quickly. The ending seemed a bit abrupt to me as well. Overall not bad, but nothing I really enjoyed either.
