I just bought "Living Low-Carb" by Fran McCullough. I haven't started it yet, but it looks good. It also includes 175 recipes.
I also bought "Back To Protein: The Low Carb, No Carb Meat Cookbook" by Barbara Doyen and "Lauri's Low-Carb Cookbook" by Lauri Ann Randolph. (all from Amazon.com). I need some new ideas for recipes.
