The Norse gods are in an uproar--Thor's hammer has been stolen! The goddess Freyja has foreseen that a human boy will help find the hammer; the Basset sails into the mortal world to find him. But when the Basset returns, it carries not one boy, but four--all of whom must change if they are to fulfill Freyja's prophecy and save the gods from destruction.
This book is part of the Voyage of the Basset Books series and is book #4 in the series.
