I don't have them for swapping, but cookbooks with more sophisticated recipes I can think of would be "Great Chefs Cook Vegan", "RawEssence", "The Blooming Platter Cookbook", "The New Vegan Cookbook", "Vegan Family Meals", "The Vegan Boulangerie", "Artisan Vegan Cheese" and "Lickin' the Beaters 2". I haven't tried them all, but those I haven't I had a good look at.
For casseroles and such, there is "One-Dish Vegan", and for spice that is flavorful rather than hot, "Vegan Fire & Spice", both by Robin Robertson, a cookbook author I appreciate.
Maybe it would help people to suggest swaps if you indicated the country you live in and the list of books you wish to swap. Also, there is a thread for cookbook swaps here:viewtopic.php?f=32&t=14202
