I think the best instructional books for a beginner are either the Orvis Fly-Fishing Guide or the LL Bean Ultimate Book of Fly-Fishing. For fun reads, you can't go wrong with any of John Gierach's books. Trout Bum would be a good starting point.
This book helped me out a lot when I first started. Covers a broad range of topics, a good primer.
