Actually, Fermat's Enigma and Fermat's Last Theorem are two separate books. The full title of the former is: Fermat's Enigma: The Epic Quest to Solve the World's Greatest Mathematical Problem (Paperback). Both books are listed on Amazon's website, again I don't think either are available as an ebook. I'm not sure of the difference. I read Fermat's Enigma as a paperback, since my daughter brought it home for a school assignment.
