Kate Messner writes for children of all ages, and this year she has three new books coming out: Marty McGuire, a chapter book about a spunky girl who would rather catch frogs than play dress-up; Sea Monster’s First Day, a picture book inspired in part by Vermont’s legendary lake monster, Champ; and Over and Under the Snow, which reveals the hidden worlds of animals in the winter. Messner is a middle-school English teacher as well as an author, and she and her family live in Plattsburgh, New York.
