Aside from the additional info we have for the Kamen Rider OOO and Kamen Rider W novels, here's the new info we have about the Kamen Rider Kabuto novel written by Shoji Yonemura.
The novel is basically the final story arc of the TV series turned into a novel. There are some extras not seen in the TV show but it is not that interesting.
The novel starts out with a 14-year old Tendou and starts jumping around to the contents from the final story arc. Even so, the scene and situation is changing all the time. You really need to have the final episodes fresh in your memory, otherwise it'll be confusing when reading it.
Nothing from the TV show is explained. No explanation where the Hopper Zecters came from or why Kagami became Gatack.
