A good book but it is a shame that they had to do diamond and pearl in 2 parts because i find myself switching between the 2 books which becomes annoying. There all some errors in the book with a few pokemon types and spelling errors, also it does not tell you about EVs which are a big thing when training pokemon to battle online which is a huge disappointment. But apart from that it is a useful book for people who do like playing the game.

Its a very very very good book, no doubt, and tell's you everything you need to know about the pokemon in there, but like the other guy said, despite the book clearly stating on the cover "Everything you need to know about all the pokemon", it misses 3 of them out, and why???

It also has quite a few miss prints in there which is dissapointing, like labelling 1 pokemon as Psychic when it is actually Electric/Ghost.

On the whole a very good book though, that will help almost all trainers. Well worth £9

All i realy need to know about it recomend 2 poke lovers
