Fires of the Forgekeep

Thor, Loki, and the others are trapped and separated deep underground, in the Forgekeep of the Dwarves. Even if they solve the maze keeping them apart, they'll have to face a Dwarven warlord, his mechanical army, and one very, very angry All-Father (also known as Thor's dad). Can Thor take control of his destiny? And the lightning? And that fancy magic hammer? Plus there's the most important, trickiest prize of all: friendship.
