Oprah is going to make a hit book even bigger.

David Wroblewski's The Story of Edgar Sawtelle, a 500-page debut novel, is Oprah's latest book club pick, two booksellers told the Associated Press this morning. Edgar Sawtelle, the story of a mute boy who communicates best with his dogs, was released in June and became a smash thanks to strong reviews, word of mouth and a blurb from Stephen King.

Winfrey was to make the announcement later today on her show. The Associated Press purchased a copy of the novel, which has a Winfrey book club sticker on the cover, from a bookseller that placed Edgar Sawtelle on sale early.
