From the day Caitlin vanishes the lives of her family members are irrevocably altered, each assuming blame for that day’s tragic events. As the initial days of hope are replaced by weeks of anxiety and despair, they find themselves increasingly isolated, each wondering: Is she still alive? Will we ever know what happened?

Pursuing every angle and refusing to surrender the belief that his daughter is still alive, Caitlin’s father struggles through the mountainous terrain, prodding both his son and the local authorities to keep up the search. It is through a most unlikely source, however, that they finally find an answer, in a climax that is stunning in both its execution and resolution.

Written with precision and elegance, Johnston captures characters’ emotions, divergent thoughts, and moments of bleak loneliness as they search for answers. Descent is both a taut and gripping thriller and a work of outstanding literary merit, a combination of great story and beautiful writing that is certain to garner comparisons with the work of such bestselling writers as Cormac McCarthy and Dennis Lehane.
