Certainly one of the more interesting books for the new Pathfinder witch class. You will need the Advanced Player's Guide to get the most of of this book obviously.
We start off with a brief overview/analysis of the witch class. Not bad really, but nothing we can get from the APG.
On to the meat of the book, the 30 new feats.
They are a mixed bag, but for the most part they add a lot flavor to the witch. There are some familiar affecting feats which is nice, and commentary/sidebars on a few.
There are also 3 sample witch builds that you can use to make your own.
All this is a good product and worth the price.
