Heroes of Olympus Series 6 Books Collection Set By Rick Riordan
The Lost Hero
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.
The Son of Neptune
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. Annabeth.
Only one thing is certain - Percy's questing days aren't over.
The Mark of Athena
Annabeth felt as if someone had draped a cold washcloth across her neck. She heard that whispering laughter again, as if the presence had followed her from the ship. She looked up at the Argo II. Its massive bronze hull glittered in the sunlight.Part of her wanted to kidnap Percy right now, get on board and get out of here while they still could.
The House of Hades
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.
The Blood of Olympus
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.
The Demigod Diaries
In this action-packed collection, runaway demigods Luke and Thalia face untold dangers on their way to Camp Half-Blood. Percy Jackson and Annabeth must rescue stolen goods from a fire-breathing giant who doesn't take kindly to intruders.
