Abigail's second year at the Tarkana Academy has been an all-out
disaster. She's just unwittingly helped Vertulious, an ancient he-witch
and powerful alchemist, destroy Odin's Stone and restore his powers, and
now all of Orkney is caught up in the threat of war as the witches
prepare to destroy the helpless Orkadians. Determined to set things
right, Abigail and Hugo set off for Jotunheim, the land of the giants,
to find a weapon to restore the balance. All they have to do is track
down the God of Thunder and convince Thor to turn his hammer over to
them.
When their former-friend-now-foe Robert Barconian arrives with a band of
dwarves, intent on stopping them, Abigail and friends must unite to
prevent a war that will destroy them all. But has Abigail made the
biggest mistake of all by trusting in the wrong ally?
