I really liked this book aside from a few niggles. One of the main things that stood out to me is that the MC's never seemed their age. I kept thinking these guys were in their late 20's or early 30's so that always seemed off. And, yes, this book takes every extreme and throws it in there, but somehow I didn't care and it worked for me. I can overlook plot points often if the characters draw me in. I wish we had gotten more backstory with Jason, but having him a mystery worked for the reader in a lot of ways too. I've been sort of bored with everything I try to read lately, and I read this in a couple hours straight through. I rooted for these guys the whole way through hoping that no matter where they ended up things would be OK for them.
