Rick Riordan previews 'Magnus Chase' sequel, 'The Hammer of Thor' and reveals cover

Chris Hemsworth's flowing hair and bulging muscles have embedded the Norse god of thunder into modern pop culture alongside Tom Hiddleston's scheming trickster god Loki. But Marvel isn't the only one remixing Norse mythology. Rick Riordan, who previously revamped Greek and Egyptian mythologies with Percy Jackson & the Olympians and The Kane Chronicles, is now taking on the Norse pantheon.
