Pilgrimage: A Post-Apocalyptic Survival Story

 James Rockwell is vacationing in Maine with his family, when an earth-changing explosion sends them on a race for their lives.  Their first step is escaping an island in the midst of a tsunami, and it only gets more dangerous from there. 

Can they find their way home as civilization crumbles around them?
It's a bullet-train of a thriller riding on the edge of the rails to the last page.
