Rolling in the Deep

I enjoyed the book, but I don't really like Mira Grant's insertion of excerpts from in-universe books and documentaries. I thought that was a shtick that was exclusive to Parasitology, but it features here as well. Unfortunately, the ending was spoiled early on by these asides, and I don't think knowing the ending did the story any favors. This appears to be a prequel, so maybe I should have already known the ending.
