It wasn't bad, it just wasn't in my particular wheelhouse. It's set in the Tim Burton PotA universe but fails to feature a single Marky-Mark.
The cover would have you thinking that the novel would be an apes vs dinosaurs action fest, but that part of the story only shows up in the last quarter of the book. The rest of the time it's a slow burn ape intrigue story about two brothers sent out to found a new colony for the apes, but one of the ape siblings has been charged with the secret task of discovering the last of their former human masters.
