Friday, July 22 will be Maine Authors Day at Mr. Paperback in the Renys Plaza, Route 3. The celebration of Maine books and writers will run from 1 to 3 p.m. and feature four authors from Maine Authors Publishing & Cooperative.

Jeff Foltz of Camden will sign “Birkebeiner: A Story of Motherhood and War.” Set in Norway in 1203, this historical novel follows Inga and her little son Hakon, heir to the Norwegian throne, as they flee on skis towards the safe haven of Nidaros, pursued by enemy soldiers bent on controlling the kingdom.

Award-winning sportswriter Kevin C. Mills of Lewiston will sign two books. “Sons and Daughters of the Ocean” steps back in time to the shipping village of Brooks Harbor in the 1870s, reliving the age of sail through the eyes of three scions of maritime families. “Sidelined” revisits Mills’ experiences with newspapers such as the Boston Globe, Portland Press Herald and Lewiston Sun Journal, showing with humor and wit the strange things that happen when a journalist is on the sidelines.

Andrew Maxcy will sign “Obsidian Shards: A Collection of Dark Fiction.” In stories ranging from sword and sorcery and dark fantasy to magical realism, characters delve into the darkness and return with knowledge forbidden by the conventional world around them.

Poet and educator Carolyn Locke of Troy will sign “Always This Falling.” In poems on topics ranging from gardening, New England winters, and jazz to Paris and aging parents, Locke’s sensitive observations of both the commonplace and the exotic take on richer meanings and show the familiar transformed.
