Following the smash-hit Olympians series, George O'Connor embarks on a new saga about the Norse gods. Welcome to the Nine Worlds, home of Gods, Valkyries, Dwarves, Jotnar, and more! Follow the mighty Thor as he thunders into battle with his trusty hammer, Mjollnir, in hand! His quests take him across fjords, hills, and the blackest Midgard sea to challenge serpents, giants, and more-but are these battles and tests of strength more than they seem? O'Connor's highly kinetic illustrations bring these gritty and astonishing tales of war, betrayal, and valor to vivid and startling life.
