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. And it turns out the gods of Asgard are preparing for war. Apparently, if I can't find the sword my father lost two thousand years ago, there will be doom. Doomsday, to be precise. A fire giant attacking the city? Immortal warriors hacking each other to pieces? Unkillable wolves with glowing eyes? It's all coming up.

Thor's hammer is missing again. The thunder god has a habit of misplacing his weapon - which happens to be the mightiest force in the Nine Worlds. But this time the hammer isn't just lost, it has fallen into enemy hands. Magnus Chase and his friends must find it, fast. If they don't, the mortal worlds will be defenceless against an onslaught of giants, and the Nine Worlds will burn. But the only person who can help them is the gods' worst enemy, Loki - and the price he wants is very high.

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. If Magnus Chase and his friends can't retrieve the hammer quickly, the mortal worlds will be defenseless against an onslaught of giants. Ragnarok will begin. The Nine Worlds will burn. Unfortunately, the only person who can broker a deal for the hammer's return is the gods' worst enemy, Loki - and the price he wants is very high.

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. Along the way, they will face angry sea gods, hostile giants, and an evil fire-breathing dragon. But Magnus's biggest challenge will be facing his own inner demons . . .

He was a God once. Until he was cast out his father, Zeus. Now, he's an awkward teenager. Called Lester. The only way out is a series of scary and dangerous trials, of course. For his third trial, Apollo must journey through the Labyrinth to free an Oracle who only speaks in puzzles. Then, defeat the most vicious of three very vicious Roman Emperors.

Half Boy. Half God. ALL Hero.It's not every day you find yourself in combat with a half-lion, half-human.But when you're the son of a Greek God, it happens. And now my friend Annabeth is missing, a Goddess is in chains and only five half-blood heroes can join the quest to defeat the doomsday monster. Oh and guess what. The Oracle has predicted that not all of us will survive . . .

Half Boy. Half God. ALL Hero. Honestly, blowing up another school was the last thing I wanted to do. As the son of a Greek God, I've had my share of near-death disaster - and now my arch enemy Luke wants to invade our camp via an ancient labyrinth. If he succeeds, thousands of bloodthirsty monsters will attack. So it's goodbye sunshine, hello darkness as four of us descend into the terrifying underground and beyond ...

Half Boy. Half God. ALL Hero.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 .

Though the Greek and Roman crew members of the Argo II have made progress in their many quests, they still seem no closer to defeating the earth mother, Gaea. Her giants have risen - all of them - and they're stronger than ever. The gods, still suffering from multiple personality disorder, are useless. How can a handful of young demigods hope to persevere against Gaea's army of powerful giants? As dangerous as it is to head to Athens, they have no other option. They have sacrificed too much already. And if Gaea wakes, it is game over

Look, I didn't want to be a half-blood. I never asked to be the son of a Greek God. I was just a normal kid, going to school, playing basketball, skateboarding. The usual. Until I accidentally vaporized my maths teacher. That's when things started really going wrong. Now I spend my time fighting with swords, battling monsters with my friends, and generally trying to stay alive.

This is the one where Zeus, God of the Sky, thinks I've stolen his lightning bolt - and making Zeus angry is a very bad idea.
Can Percy find the lightning bolt before a fully-fledged war of the Gods erupts?

Half Boy. Half God. ALL Hero.You can't tell by looking at me that my dad is Poseidon, God of the Sea.It's not easy being a half-blood these days. Even a simple game of dodgeball becomes a death match against an ugly gang of cannibal giants - and that was only the beginning.Now Camp Half-Blood is under attack, and unless I can get my hands on the Golden Fleece, the whole camp will be invaded by monsters. Big ones . . .
