The headline act is Dion and the Goat Guys, and Zeus has a funny feeling this Dion guy might be one of them. What kind of magical powers does this Dion kid actually have? And will he be more of a help--or a pain--in their ultimate quest to defeat King Cronus once and for all?"--Provided by publisher.
