Most people get presents on their sixteenth birthday. I get a prophecy that could save or destroy the world.

It happens when you're the son of Poseidon, God of the Sea.According to an ancient prophecy, I turn sixteen and the fate of the entire world is on me. But no pressure.

Now Kronos, Lord of the Titans, is beginning his attack on New York City. And the dreaded monster Typhon is also heading our way. So it's me and forty of my demi-god friends versus untold evil . . .

The first book in the incredible new series from the author of Percy Jackson, the Kane Chronicles and Heroes of Olympus.My name is Magnus Chase. I'm orphaned and living rough on the streets of Boston. And things are about to get much worse.My day started out normally enough. I was sleeping under a bridge when some guy kicked me awake and said, 'They're after you.' Next thing I know, I'm reunited with my obnoxious uncle, who casually informs me that my long-lost father is a Norse god.Nothing normal about that.

Rick Riordan's Norse hero faces his greatest challenge yet in the final instalment of the series.Loki the trickster god is free from his chains. Now he's readying Naglfar, the Ship of the Dead, armed with a host of giants and zombies, to sail against the Norse gods and begin the final battle of Ragnarok. It's up to Magnus Chase and his friends to stop Loki's plans, but to do so they will have to sail across the oceans of Midgard, Jotunheim and Niflheim in a desperate race to reach Naglfar before it's ready to sail on Midsummer's Day.
