When retired U.S. Army chaplain Greg Sponney left for a three-month sailing and hiking adventure cruise, he never could have imagined that he would one day be shipwrecked and stranded on a small, rocky, uninhabited island in the northern Pacific Ocean.

This is his story, in the form of 64 letters to his seven grandchildren, in which he describes his survival adventure. He also seeks to share with them what he believes is important in lifehoping that somehow, someday his grandchildren will have the chance to read them.

Torn between despair that he will never be rescued, and hope that he will, he and his two fellow-survivors, a retired carpenter and a retired nurse, make the best of a desperate situation.
