Local author Dorie McCullough Lawson will sign copies of her first children’s book, “Tex: a book for little dreamers,” Saturday, Oct. 1 from 10 a.m. to noon at Owl & Turtle Bookshop, 32 Washington St.

What happens when a little boy who lives near the ocean dreams of tall mountains to climb, wide open fields to run through, dusty boots to stomp and a pony for a best friend? He becomes Tex, a rugged little cowboy with a great big job working on the Wymont Ranch. Each day is full of important responsibilities: Tex has animals to look after and ranch chores to do.

“Tex” is based, in part, on the adventures Lawson’s son Luke had on the Wymont Ranch in Wyoming during his early childhood. Illustrated with beautiful and authentic photographs taken of Tex/Luke during family visits to the ranch, Lawson said she simply followed him around and photographed everything and the story came out of the photographs.

Lawson lives in Rockport with her husband, painter T. Allen Lawson, and their four children. Daughter of the writer David McCullough, she is the author of “Posterity: Letters of Great Americans to Their Children” and “Along Comes a Stranger: A Novel.” “Tex” is her second book set in the American West and her first book for children.
