I bought this book, because well, I'm a feat nut. I love the options feats give you. I've made it through well over half the book now, and I am sorely disapointed.
No bookmarks….And there is a list of the feats in that “chapter” (by chapter, I mean alphabetical). No offense, but if they are reading this pdf (or even this review!), then they know their letters.
Some of the wording is so odd that you wonder if they have even PLAYED D&D. And at times, the proof reader didn't do their job (missing words on occasion, “equipment bonus” from your armor). Some of the feats that are Metamagic, I wouldn’t consider metamagic either, such as Binding Counterspell (which if you counter a spell of an opponents, a negative effect also occurs on them, which is a cool idea, just not a metamagic feat)
Over all, the feats are either too specialized or over powered. There's been quite a few "sexual" feats as well as ones dealing with women's, ahem, "time of the month".
Out of the 160ish feats I have read so far, I would say maybe 20 were good solid feats. If you want some more options, pick it up, otherwise, it is kind of a waste.
