A Horse's Tale by Susan Lubner

A Horse's Tale (A Colonial Williamsburg Adventrue) by Susan Lubner, illustrated by Margie Moore, Abrams Books for Young Readers, 2008, ISBN 978-0-8109-9490-4
Publisher's Summary: In Williamsburg, Virginia, in colonial days, Lancer the horse runs loose and behaves oddly while his owner and owner's friends try everything they can think of to help him feel better, until Margaret the Milliner realizes that Lancer needs a friend, too.
The value of this book lies in its depiction of colonial towns, lifestyles, and occupations. The glossary in the back defines "apothecary", "counterpane", "milliner", and "shod", to name a few. Would work with 5th graders study of Colonial America.
