"Please come to Camelot"
When they read this note, Jack and Annie know they must travel to Camelot and the castle of King Arthur: The magic tree house whisks them through time and space, where they find that the castle has been attacked and King Arthur himself has been gravely wounded.
To save the kingdom - and the king- Jack and Annie must solve a riddle, trick a band of robbers , and journey to the worlds of myth to find a missing dragon. And everything has to happen in less than one day!
