The book Sawyer was reading on the beach.

Kim, this may not be your favorite picture of Sawyer, he looks kinda geeky. But, the book he is reading may hold another clue to lost. Here is a description of the book:

Lancelot Lamar is a disenchanted lawyer who finds himself confined in a mental asylum with memories that don't seem worth remembering. It all began the day he accidentally discovered he was not the father of his youngest daughter, a discovery which sent Lancelot on modern quest to reverse the degeneration of America. Percy's novel reveals a shining knight for the modern age--a knight not of romance, but of revenge.

I know that even the smallest of something in this show is a clue to something bigger.
