The book has been reviewed in details by Dark Mistress so I will just add my bit.

Overall it's a good book. By reading at the book I thought this would be only for Clerics and Druids. In fact there are many feats which could be used by any character who believes in a Deity.

Some could really be fun, like Blood or death priest.

Really that's a good book and I recommend it. In my opinion the price is the only reason why i didn't give 5 stars. Mind you not that 2.99$ will kill me....

My players already love it.

Closing thoughts. I like this product, while it is mostly for divine casters, several of the feats can be taken by anyone devoted to their god. Allowing them spell like abilities or even to learn limited spell lists. There was a couple of spells I didn't agree with, Natures Pries is the one I had the most problems with. Mostly due to it takes 8 hours of rest to gain a natures mark(what you need to cast a spell) in the terrain you choose and you lose one if you sleep in any other terrain. That makes the feat very niche, if you are adventuring in that terrain it is a good feat, if you are anywhere else it gives you nothing. I would have liked to have seen it changed to any wilderness and only losing points if you sleep in a very urban environment or another plane.

Anyways other than a few nitpicks like that, I felt the feats where well done. The art ranges from meh to good. So I am giving this one a 4 star review. While I liked it, I did have a few nitpicks about the product.
