I had hoped for a bit more romantic development after the first book, but this one was another slow burn along with the paranormal action and sus SPECTR stuff. My main gripe with this book is that I felt that I didn't get to know the character's thoughts and reflections on a lot of the stuff that was going on – like what Caleb thought about John calling him babe so often, or how John felt about Caleb being "offered" the contractor role at SPECTR, and his colleagues' attitudes towards Caleb. This made it harder for me to connect to the characters and their relationship, since I'm not getting much insight and development. The book was an okay, fairly short read, but I don't think it's gotten me hooked enough to continue the series.
