Beginning with the end in mind; I just read Buck, Buck, Moose by Hank Shaw.
I should preference this by stating that my wife is a chief and she's a bit elitist when it comes to proper cooking technique. I've purchased a lot of wild game cookbooks and most of them are just kind of okay. Most are home cooks and that's good, but they miss the methods of how and why something is done.
Hank Shaw's Buck, Buck, Moose illustrates proper cooking techniques, modified dishes that have been adapted to use a more lean meat source, really old dishes using a verity of cuts including organ meat, regional cooking differences for verity and has a bit of old soul flare.
I would recommend this book for any hunter, hunt camp and will be purchasing his other works.
