Feats and Prestige Classes are two elements that 3rd edition introduced to the D&D game to make customization easier for a given character. Since then there has been a glut of both. There really is not much to say about this pdf beyond telling it's a bunch of feats. Very simple and fairly versatile. The majority of the feat dovetails with the two combat style rangers can choose from and a few that a fighter can get as one of her bonuses. Feats are something that while there is a lot of them, most of them are as such that you want to consider looking at them to see if this is where you want to go with your character.
A note to the ones who made this: I'm not really interested in most of the series as pdfs but if you combine everything into a pamphlet for some place like Lulu as a print on demand, I would highly consider getting it. That and the Twilight book. I bought the Exodus book through Lulu for 3.5 so if you put out books on Lulu I will get them. Buying them here is a taste, an appetizer. I want the full meal.
