And Foodporn's Robyn offers some Indian recipe books (I've used the first and it's terrific).
Two review/links that i haven't gotten onto FoodPorn yet and should be
because they're the best Indian cookbooks:
Madhur Jaffrey's Indian Cooking:
Madhur Jaffrey's World-Of-The-East Vegetarian Cookbook
(those links are my affiliate links for foodporn, you can drop that part
of the URL if you want) :)
But those are essential cookbooks for really good indian food!
(you should know you'll hear from me if you write about food)
