Ok, this guide will not tell you how to find all the secrets or all the legendaries. However it does complete the 150ish pokedex nicely and round off the story mode. Some of the book is arranged slightly strangely, appears not to be in order, however, once the user has obtained fly and the amount of times you go back to cities it really doesnt matter where in the book it is, because you have to search for it anyway. It has great maps of areas though. Which is great!I recommend for the price!
