River for the Unrequited

Harried writer, Bernard Goldman, is about to discover that the greatest challenges are those that are closest to home.
Somehow, he gets roped into an eco-rafting trip down the pristine Jennings River in Yukon, to bond with his son, Sergeant Sean Goldman, who suffers from extreme PTSD after a disastrous tour in Afghanistan.
But can the wilderness adventure heal the hidden cracks in Bernie's marriage, help Sean find his way, and give Bernie a path forward to reconcile with his famous father, Ephraim?
