Closing thoughts. The art work runs from good to top notch in this product. The monsters are interesting. If you are a fan of the dark fey and things like Grimms tales, this product will help bring that feel to your game. If you are looking for that or just some new interesting monsters then I highly recommend this product. The CR ranges from 1/3 to 21, with all but three of them being between 2-10 CR. Only one at 13 CR and one at 21 CR. I would like to see a follow up to this product, perhaps a part 2 with more fey and/or a fluff heavy book about the fey realm and more fluff about the creatures.

I did notice one thing odd that I am not sure if it was done on purpose or not. In the Vodnick section there is looks like there is drops or circles where the text is just a bit blurry, not enough where it is still not easy to read but enough to be very noticable. I am not sure if that is suppose to be drops of water on the page as they are aquatic fey or not. That appears to be the case and I think it was done on purpose but I am honestly not sure.

So whats my rating? Well I couldn't really find anything wrong, but to be fair I am not a huge number cruncher when it comes to stat blocks. As long as it looks like it will play well I am content. But I didn't notice any stat block errors either. My only real complaint is I wish they had had about half a page or more of fluff for each monster, I think that would have turned this from a great product to a fantastic one. So with the top notch art and interesting fey monsters and no real errors to speak of. I am giving it a 4.5 star review.
