Loki, the god of mischief, is Thors troublesome adopted brother. Odin, their father (and ruler of the Viking gods), orders the quarrelsome siblings to tame the violent Giants once and for all--together. But what Loki and Thor find in their series of adventures puts them in conflict with each other as well as with the giants. And in the land of Utgard, a mysterious place made from magic and illusion, Thor must trust his magic-wielding and misbehaving brother in order to get out alive. Likewise, Loki must count on his brothers unmatched strength if he, too, hopes to survive their encounters with the Giants.
