My friend is a vegan. Can you recommend a good cookbook for vegans?

I would recommend the book "Veganomicon" by Isa Chandra Moskowitz and Terry Hope Romero. It contains over 200 recipes that are all vegan, including breakfast, lunch, dinner, snacks, desserts, and beverages. Plus, it has helpful tips on how to prepare vegan meals and suggestions for substitutions when needed.
