That's the thing about magic -- it's only real if you believe in it.

The Island of Mist is under siege and Prince Ben and his best friend Odge Gribble -- a hag -- are in hiding. Desperate to find out why the island's protective mist is disappearing, Odge travels through an enchanted gump to Vienna, in search of a mistmaker expert.

But instead Odge finds Lina, a nine-year-old girl looking for adventure. With the help of friends old and new and some very interesting magic, Odge and Lina must discover the secret of the mist, before they lose their beloved island completely.
