This book spoils the whole plot. it tells u everything that's going to happen, and it dosn't even have good tips on how to beat emerald weapon, ruby weapon, and ultimate weapon. It also doesn't have any good tips on how to raise chocobo's. It dosn't even tell u about the verry last boss. it tells u about the 2 diferent forms of sephioth.but it dosn't tell u how cloud goes off and faces sephiroth on his own with no materia.The only reason i would recomend this to u is if ur trying to beat the game for the first time. And even then it still is kinda bad.
