Something terrible happened seventeen years ago. Red, the sheriff, is haunted by it. Possum, the victim of that crime, wants revenge. Chase, a former friend of Transom's, is devastated by his treacherous land dealings. And Laney worries her one thoughtless mistake with Transom could shatter everything she's built.

As the search for Transom heats up and the inhabitants' dark and tangled histories unfold, each must decide whether to live under the brutal weight of the past or try to move beyond it. In Fallen Mountains, even loyalty, love, trust, and family can trap you on a path of tragedy.
