Query: Good book

This book has some really decent new spells for all classes that aren't too overpowering given the levels they are at. A lot of the prestige classes are a bit far out there, given some of their backgrounds you need to have. There are semi-okay feats, but they appear to be mostly add-ons to prior types with more accurate advantages than would be presumed if you tried to make them up yourself.All in all: Useful for prestige and new spells, which is why I bought it. Beyond that it might need more, but I don't know of those needs.
