I just finished Firestorm yesterday and I enjoyed it a lot! What I noticed in the book was that the characters of Koba and Dreyfus were developed, and made to be sympathetic. I think this was very purposful, because these are going to be the prejudiced members of their communities,and Matt Reeves emphasized he wanted no villians, and this book serves to show how Dreyfus and Koba aren't villians but want what they think is best to protect their species.
The only thing I didn't like was that it didn't show what happened to Will Rodman after Rise of the Planet of the Apes which would have been interesting to see.
I also liked the references to the original, with Milo and the Alpha-Omega Group, referencing the bomb in beneath. Were there any other references/ And what do you guys think of the book?
