Grisham holds on to non-fiction Best Seller list too

It probably won't surprise readers to learn that John Grisham's latest book is still doing remarkably well at the register. Maybe it should.

The bestselling author (who announces today that he'll judge the Hook's 2007 short story contest) has penned legal thrillers including The Firm and The Client, many of which have been runaway successes in both bookstores and at box offices. But his latest work was a little more of a gamble.

The Innocent Man is Grisham's first book of non-fiction, chronicling the experiences of Oklahoma resident Ron Williamson as he tangled with local police over a murder case, lost in the subsequent trial, and spent more than a decade on death row before being exonerated by DNA evidence in 1999.

After Grisham released the book in early October, it quickly shot to #1 on the New York Times best-seller list. Three and a half months later, it's still holding on strong at #2, topped only by Illinois Senator (and likely 2008 presidential candidate) Barack Obama's The Audacity Of Hope.
