Left Bank Books will host a signing and children’s party with author Dorie McCullough Lawson Saturday, Dec. 3 at 10:30 a.m. at the downtown book store, 21 East Main St./Route 1.

The event celebrates Lawson’s new children’s book, “TEX! A Book for Little Dreamers.” Admission is free and the entire community welcome, especially preschoolers and would-be cowboys and girls.

Lawson, who lives in Rockport, is the daughter of historian David McCullough and the author of two acclaimed books for adults: “Posterity: Letters of Great Americans to Their Children”; and “Along Comes a Stranger, “a mystery based on the story of Whitey Bulger. “TEX!” is her first book for children and a wonderful read-aloud for the 3-to-5-year-old set. It stars a little boy named Luke, based on Lawson’s own youngest son, who lives near the ocean but dreams that his name is Tex and that he lives on  the range. Tex is one serious rancher, herding cattle, digging irrigation fields, caring for his pony Thunder and his cowdog Sue,  fixing fences and dressed in a jean shirt, boots and a black-brimmed hat. As Luke, of course, he is dressed in flannel pajamas and snug in a bed made with cowboy-print sheets. With the briefest of texts, and Lawson’s own color photographs, “TEX!” celebrates the power of a child’s imagination as well as the beauty of the American west.

To celebrate the new book, there will be a special sale at the shop with 20 percent off all children books (save “TEX!”) and toys for the day. To reserve a copy or for more information, call Left Bank Books at 548-6400. The shop is open daily.
