When Jason, Piper and Leo crash land at Camp Half-Blood, they have no idea what to expect. Apparently this is the only safe place for children of the Greek Gods - despite the monsters roaming the woods and demigods practising archery with flaming arrows and explosives. But rumours of a terrible curse - and a missing hero - are flying around camp.

Ever since the gods of Ancient Egypt were unleashed on the modern world, Carter Kane and his sister, Sadie, have been in big trouble. As descendants of the magical House of Life, they command certain powers. But now a terrifying enemy - Apophis, the giant snake of chaos - is rising.

Percy Jackson fought Greek Gods. Now the Gods of Egypt are waking in the modern world... 'I guess it started the night our dad blew up the British museum...' Carter and Sadie Kane's dad is an Egyptologist with a secret plan that goes horribly wrong. An explosion shatters the ancient Rosetta stone and unleashes Set, the evil god of chaos...

The stakes have never been higher. If Percy Jackson and Annabeth fail in their quest, there'll be hell on Earth. Literally. Wandering the deadly realm of Tartarus, every step leads them further into danger. And, if by some miracle they do make it to the Doors of Death, there's a legion of bloodthirsty monsters waiting for them.

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.

Carter and Sadie Kane, descendants of the magical House of Life, are in pretty big trouble. Despite their bravest efforts, Apophis, the giant snake of Chaos, is still threatening to plunge the world into eternal darkness. Now the Kanes must do something no magician has ever managed - defeat Apophis himself. No pressure there then.

Percy Jackson, son of Poseidon, God of the Sea, has woken from a very deep sleep and come face to face with two snake-haired ladies who refuse to die. But they're the least of his problems. Because Percy finds himself at a camp for half-bloods, which doesn't ring any bells for him. There's just one name he remembers from his past.

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. Now I spend my time battling monsters and generally trying to stay alive. This title tells the author story.

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.
