Abbot laboratories is giving away an informative book about Crohn's Disease called 100 Questions and Answers about Crohn's Disease and Ulcerative Colitis. Here is the link for the page to sign up to receive the free book from Abbot.
I ordered this book last year and read it from cover to cover. It is a good book, although it is not very new and therefore does not cover some of the newest biologic treatments such as Humira. But its still a great reference, especially for a family member who wants to know what its like for the person who has IBD.
