“Magnus Chase and the Gods of Asgard: The Sword of Summer” by Rick Riordan

If you’ve ever stayed up past midnight reading Percy Jackson, or handed it to a kid who did, here’s your next obsession.

Magnus Chase has spent two years living on the streets of Boston since his mother’s mysterious death. Then an uncle he barely knows tracks him down with an impossible secret: Magnus is the son of a Norse god. The Viking myths are real, the gods of Asgard are preparing for war, and the wolves of Ragnarok are on the move. To stop the end of the world, Magnus has to find a sword that’s been lost for a thousand years.

Riordan does for Norse mythology what he did for the Greeks: big laughs, real heart, and nonstop action. Thor, Loki, and a wisecracking talking sword are just the beginning. Percy Jackson fans will spot a familiar family name, too.

This hardcover with dust jacket is in very good condition and includes a sneak preview of “The Dark Prophecy.” It’s available at Dead Tree Dreams, in-store and online.
