Westwinds Bookshop at 35 Depot St. will hold a reading at 3:30 p.m. Saturday of a new holiday children’s book, “The Lighthouse Santa,” based on the life of an important local figure. Historian and storyteller Edward Rowe Snow carried on the tradition of the South Shore and Boston Harbor “Flying Santa” from 1936 to 1980. Every Christmas, Snow would hire a small plane and drop wrapped gifts to the region’s lighthouse keepers and their families. Author Sara Hoagland Hunter will read from “The Lighthouse Santa,” a picture book about Snow’s deliveries. Illustrator Julia Miner will show her work and explain her creative process.
