The Confession - John Grisham

For every innocent man sent to prison, there is a guilty one left on the outside. In 1998 Travis Boyette abducted, murdered and buried a high school cheerleader, then watched in amazement as police and prosecutors arrested and convicted Donté Drumm and marched him off to death row. Nine years have passed. Travis has just been paroled for a different crime; Donté is days away from execution. Travis suffers from an inoperable brain tumor. Travis decides to do what's right and confess. But how can a guilty man convince everyone that they're about to execute an innocent man?
