Book excerpt: When Mordred announces a three-day weekend for DSA, Wiglaf and his friends (including his Pig Latin–speaking pig, Daisy) are off to Erica’s castle. But when they arrive, they discover that Erica’s father, King Ken, has come down with a horrible case of liver pox. The wizard Zelnoc manages to cure the king’s pox, but as with all the wizard’s spells, there’s a magical mishap. Now, King Ken can only speak in Pig Latin! Can Zelnoc fix his mistake, or is there a better chance that pigs will fly?
