The life of ten-year-old Zac Sparks changes overnight when his mother is killed by lightning. He's sent to live in Five Corners with his Aunties, two cruel old hags who obviously don't like him. It isn't long before Zac knows something really strange is going on. Five Corners is populated with weird characters--a midget butler, a girl who doesn't speak, a blind balloon seller, and a mysterious singer who is heard but not seen. Then there's the Aunties' father, Dada. Zac's first encounter with Dada is so terrifying he faints dead away.
The one bright spot is Sky Porter, the proprietor of the general store across the street, a friendly soul who encourages Zac--when the Aunties aren't looking--and shows him a kindness that is sadly lacking from his dismal life. But Sky isn't what he seems either, and when Zac learns Sky's amazing secret he realizes, to his dismay, that this wonderful man may have a very dark side as well.
Discovering that Dada is an evil magician who is intent on stealing the ultimate treasure, Zac knows many lives are at stake, including his own. With time running out, he must turn to the one person who might be able to help: Sky Porter. Can Zac trust him?
