It wasn't really a Ratchet and Clank book, it was more a general "CreatureBox" book... I should see if I can link you to it. It was in their store last I checked.
[link] It was this one! It looks to be sold out, and apparently was even on sale. I bought mine at full price a month or so back. Ahaha. Maybe they'll release another one next year. If so, I might just have to pick it up.
SUCH LOVELY SCENES ;_____; The emotion in the bottom picture made me so....D:...GAH when I saw it in the game!~ Therefore; this is awesome c: I ALSO LOVE all the pipes and mechanical stuff in the foreground Looks sweet!~~~~
