This extremely attractive book is full of all sorts of new spells, feats and magic items for all the spell-casting classes in Pathfinder (or the 3.x product of your choice).
The vast majority of this book is devoted to spells and there a spells here for every need and situation. There a few new feats and some magic items, but the spells here are the main course.
There are several useful Appendices including Spells by Descriptor, School and use.
At 12 bucks this product is not exactly a steal, but really, really close. The art and layout is fantastic and you get a printer friendly version as well.
