This review is from: Pokemon Black and White Versions: Official Unova Pokedex & Guide v. 2 (Paperback)
It's the official guide, so it's well done.
Has all the Unova pokemon, lots of detail for them, plus tips for the game
It doesn't include a game walkthrough, and doesn't have pokemon from the previous four generations in it.
You can manage without it - bulbapedia and other sites are fantastic free resources - but it's nice for a real pokefan to have.
