Well, it really depends on what you are wanting out of them.
If you want a great read by a very obviously well written, worldly guy, get any of the bowhunting based books by E. Don Thomas. I believe I have read them all and I will be branching out to his other books soon. I really like his style with words.
His are stories of his experiences, one exception, the one titled "How Sportsmaen Saved the World", which is a read that should be required for all hunters and fishing persons. It is about our recent American history and very well presented.
Another author I have come to appreciate is David Petersen. Although if we were together for five minutes, there could be a bout of fisticuffs (I don't always agree with him and he often comes across as right, no matter what) I do like reading his words, he has a way with them. Actually, I would seriously like to meet him and share a campfire and a few amber libations and actually MEET him. He also tells of his experiences as well as the results of some of his research time.
If you are a real glutton, try reading Meditations on Hunting, by Gassett. I did it (finally) and all I can say is. . wow. Amber libations before and during help with this one.
Of course, there is The Witchery of Archery, and A Sand County Almanac, both classics.
And there are a whole book rack full of others that a good reads, again, depending upon what you seek.
Good luck
