Others have already made the standard book recommendations. You will get something from most all of them. Hought's books are step by step cook books, that works good when you have no idea what to do. The downside is that if you miss a step you can get real lost and they don't do a very good job of teaching you how to figure out the knots. Grant's books are very good at teaching you how to figure out things, but they can sure be a bear to follow until the light goes on then they maybe the best of the lot.
One thing I haven't seen anyone recommend yet is go buy a bunch of paracord and practice practice practice. The paracord is great because you can use it over and over and use it to prototype things quickly. On the downside it is way more forgiving if you twist a string so it will teach you the braids and knots but doesn't help you keep your string rightside up. After you have some of the braids down start cutting up some hide, plan on lots of it going in the trash.
