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. The Son of Neptune: Percy Jackson, son of Poseidon, has 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. One thing is certain - Percy's adventuring days aren't over. Mark of Athena: In The Son of Neptune, Percy, Hazel, and Frank met in Camp Jupiter, the Roman equivalent of Camp Halfblood, and traveled to the land beyond the gods to complete a dangerous quest. The third book in the Heroes of Olympus series will unite them with Jason, Piper, and Leo. But they number only six--who will complete the Prophecy of Seven? 9780141359984/9780141370507/9781368051422
