The Gluten-Free Bible by Jax Peteres Lowell. Covers a wide range of issues from attitude to shopping to dealing with family members.
Wheat Belly by William Davis. This is a very popular book that looks at the connection between wheat and poor health. It looks at neither celiac nor gluten allergy but proposes that wheat is bad for your health generally. It has a small section on avoiding wheat but mostly looks at the negative health effects of wheat. There is a separate cookbook called Wheat Belly Cookbook which I have not tried and so cannot comment on.
This is by no means a comprehensive list of books about gluten free living. See also Food Allergy Cook Books on this site.
