To keep the flavor profiles simple and some basic tips on technique I would go for: Smoke and Spice by jamieson (for low and slow cooking). For grilling I second the Adam Perry Lang book and two Purviance books above but would also add Weber's charcoal cooking and Weber's Real Grilling, with a preference on charcoal grilling (the recipes are easily converted to gas if that is the preference). Also check out Raichlens books, both The BBQ Bible and How To Grill and Sacues Rubs and Marinades. Also good is Jim Tarantino's Marinades, Rubs, Brines, Cures and Glazes. And finally Born to Grill by Jamieson is a decent book with easy recipes. Clark
