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. When Jack and Annie receive an invitation to spend Christmas Eve in Camelot, a magical place that exists only in myth and fantasy, they know they are in for their biggest adventure yet. What they don't know is that the invitation will send them on a quest to save Camelot. Can they succeed even though Camelot's greatest knights have failed and prove to a beleaguered King Arthur that children and imagination really can make a difference?
