I got Vegan Freak from the library, and it was done well. It came from an intellectual standpoint, not a free the whales or hippie standpoint... it was all from reason to action.
Not on nutritional info level, but on good things to cook, my new books I'm LOVING are: Veganomicon, Vegan With a Vengeance, Vegan Cupcakes Take Over the World, The Ultimate Uncheese Cookbook, and The Joy of Vegan Baking.
Between those, I can find just about anything I need. I do still turn to Vegetarian Cooking for Everyone, for basic basic info, like how long to cook the average potato when baking, and at what temp do you roast oven fries, etc.
