CHRISTMAS IN CAMELOT The Magic Tree House series has become a staple for inspiring kids to read. Christmas in Camelot is a very special Magic Tree House book. Here, author Mary Pope Osborne uses the literary skills for which she’s known to create a longer, more in-depth story featuring the characters kids have come to love. The result is magical: a fast-paced but detailed, easy-to-read story. Jack and Annie go on a quest to save Camelot, a quest that will prove to a beleaguered King Arthur that children and imagination really can make a difference.
