It's not quite the bombshell that J.K Rowling committing to writing "Harry Potter: The Adult Years" would be. But Oprah Winfrey's announcement that she'll once again feature present-day authors in her book club has to be close to that for publishers.

The daytime talk queen announced her newest selection -- James Frey's memoir "A Million Little Pieces" -- on her show Thursday (Sept. 22). The book's publisher has ordered an additional printing of 600,000 copies, and the book now sits at No. 1 on the Amazon.com sales chart.

The choice of "A Million Little Pieces" is a "radical departure" for the book club, Winfrey said on the show. "It's not a classic and it is also not fiction but a bold choice ... it's a gut-wrenching memoir."

Winfrey started her book club in 1996 and helped several dozen books, including works by Toni Morrison, Wally Lamb and Alice Hoffman, become bestsellers. She suspended the club in 2002 but started it up a year later, focusing on classic literature from the likes of John Steinbeck, Gabriel Garcia Marquez and Pearl S. Buck. This past summer she recommended three books by William Faulkner.

Frey's mother was in the "Oprah Winfrey Show" audience Thursday. As Winfrey began talking about "A Million Little Pieces," she shouted, "That's my son!"
