Incredibly good series, but numerous grammatical errors throughout. They're easy enough to overlook. Some words are wrong altogether but you can figure out what they were supposed to be. There was one glaringly obvious word choice that was wrong and couldn't be explained away by autocorrect. In location 10690, Stark is said to have a "didactic" memory. From the context, the author clearly meant "eidetic memory" (a.k.a. photographic memory).
The final installment of the Bull's Eye Sniper Series was another ride with thrills, loss and crazy cult battles. Lopez, always a star in these books and my favorite character, actually did some growing up in this cycle proving he's not just a crazy adrenaline junkie. I'm looking forward to the next cycle and the return of Brandt and Rebecca.
