I didn't really enjoy the primary relationship in this book, I didn't think it was developed well enough. Kell & Teddy seemed to jump into bed and fall in love based on sex; I didn't really see any other reason why they liked each other. Teddy seemed like kind of a whiny, weak heroine to me so that was probably a big part of the problem. The plot on this one was also kind of convoluted by the end. While this was my least favorite in the Shadow Force series, I enjoyed the secondary relationship between Reid & Grier, and I'm actually looking forward to reading their story when it comes out. Overall, this book wasn't bad, it just wasn't anything special either.
