Magnus Chase, a once-homeless teen, is a resident of the Hotel Valhalla and one of Odin's chosen warriors. As the son of Frey, the god of summer, fertility, and health, Magnus isn't naturally inclined to fighting.

Zeus has punished his son Apollo — god of the sun, music, archery, poetry, and more — by casting him down to earth in the form of a gawky, acne-covered sixteen-year-old mortal named Lester. The only way Apollo can reclaim his rightful place on Mount Olympus is by restoring several Oracles that have gone dark. What is affecting the Oracles, and how can Apollo do anything about them without his powers?

Thor's hammer is missing again. The thunder god has a disturbing habit of misplacing his weapon - the mightiest force in the Nine Worlds. But this time the hammer isn't just lost, it has fallen into enemy hands...

How do you punish an immortal?

By making him human, which leads to interesting events...

Magnus Chase has always been a troubled kid. Since his mother’s mysterious death, he’s lived alone on the streets of Boston, surviving by his wits, keeping one step ahead of the police and the truant officers.

One day, he’s tracked down by a man he’s never met — a man his mother claimed was dangerous. The man tells him an impossible secret: Magnus is the son of a Norse god.
