Have seen a lot of reviews slating this guide in regards to having no post game or Pokedex.
This is common practice since Pokemon Red & Blue days to not have a post game or Pokedex guide from this publisher as this information comes as a separate book. See my product link below.
Other than that this guide is fine for getting the main game and getting on the road straight off. No problems.Pokemon X & Pokemon Y: The Official Kalos Region Pokedex & Postgame Adventure Guide: the Official Pokemon Strategy Guide
