Civil War On Sunday (Magic Tree House #21)

Traveling back in time from the rumbling thunderstorms of present-day Frog Creek, Pennsylvania, to the booming of Civil War cannonballs near Richmond, Virginia, Jack and Annie set out on their 21st Magic Tree House adventure. The mysterious Morgan le Fay, magical librarian of Camelot, the long-ago kingdom of King Arthur, has left the brother and sister a message in their magic tree house, asking for their help saving Camelot. "Please find these four special kinds of writing for my library: Something to follow, Something to send, Something to learn, Something to lend." Jack and Annie enthusiastically transport themselves to a field near the fighting, and soon are enlisted as volunteer nurses assisting none other than Clara Barton, legendary "Angel of the Battlefield," as she drives her horse-drawn ambulance right onto the battlefields to help save wounded soldiers--including one with a very special connection to Jack and Annie.

Mary Pope Osborne's tremendously popular Magic Tree House series launches into a new realm, as Jack and Annie are challenged to save Camelot. Young readers will effortlessly learn the basics of Civil War history, while losing themselves in another gripping tale that has turned many a nonreader into a bookworm.
