His wife Stephanie reveals she is unhappy in the marriage and takes their teenage son to visit her sister in PA. Brooke's former best friend, Aaron Reardon, still devastated from Brooke's disappearance, offers to help. And forever lurking in the background is Mike Rakowski, Brooke's ex, a possessive, abusive drug addict.
As Robert's world unravels, he revisits that night twenty-one years ago where everything went wrong, unearthing a horrible, bone-chilling secret. In the vein of Simone St. James' Sun Down Motel and other female-driven domestic psychological thrillers today, ALL WHO WANDER mines the depths of past transgression, begging the question: do past sin automatically negate future happiness?
