Lincolnville author Scott Dickerson will be signing copies of his new novel “Telling Stone” from 1-3 p.m. Saturday, Dec. 17 at Sherman’s Maine Coast Bookshop, 158 Main St. in Damariscotta.

“Telling Stone” is a deep immersion in Paleolithic people and the art revolution they created 23,500 years ago in northern Spain. Why did they make these magnificent carvings and paintings? How did their hunter-gatherer band live in an ice-age environment?

Archaeologists have discovered a great deal about these hunter-gatherers, indicated by stone, bone and other artifacts. But no one can know how they thought, related with each other or were motivated to create art. These mysteries are fertile terrain for imagination, as stated in a news release.

“Telling Stone” is a story told through realities of the hunt, conflict between band members, fears for survival, sensuality of hearthmates, and what they expressed on stone walls using flint tools and paint. And why.

Dickerson is a conservation biologist, designer and maker of fine furniture, and an organic farmer. His first book, “To Save a River,” tells the story of endangered Atlantic salmon in Maine’s Ducktrap River. “Telling Stone” is his first novel, published by Maine Authors Publishing & Cooperative in 2022.
