The official world record for the length of time spent underground is held by Michel Siffre, at 205 days. But during the Holocaust a community of thirty-eight Jews spent 344 days hiding in huge network of caves.

The Secret of Priest's Grotto tells about cavers Peter Lane Taylor and Christos Nicola learning about the story, meeting survivors, and going back to the cave and discovering proof of their tale.

The families that went into the caves included young children as well as grandparents. Some of the men went out to gather supplies, and they lived in fear of discovery. Those in the caves determined to survive and to live for their families.

This book includes pictures of the caves now as well as the families in happier times before the war. An amazing story unfolds of what people will do for their families.
