Book One: The Lost Hero
Jason has a problem.
He doesn’t remember anything before waking up in a bus full of kids on a field trip. Apparently he has a girlfriend named Piper, and a best friend named Leo. They’re all students at a boarding school for “bad kids.” What did Jason do to end up here? And where is here, exactly?
Piper has a secret.
Her father has been missing for three days, ever since she had that terrifying nightmare about his being in trouble. Piper doesn’t understand her dream, or why her boyfriend suddenly doesn’t recognize her. When a freak storm hits during the school trip, unleashing strange creatures and whisking her, Jason, and Leo away to someplace called Camp Half-Blood, she has a feeling she’s going to find out.
Leo has a way with tools.
When he sees his cabin at Camp Half-Blood, filled with power tools and machine parts, he feels right at home. But there’s weird stuff, too—like the curse everyone keeps talking about, and some camper who's gone missing. Weirdest of all, his bunkmates insist that each of them—including Leo—is related to a god. Does this have anything to do with Jason's amnesia, or the fact that Leo keeps seeing ghosts?
Book Two: The Son of Neptune
Percy is confused. When he awoke from his long sleep, he didn't know much more than his name. His brain fuzz is lingering, even after the wolf Lupa told him he is a demigod and trained him to fight with the pen/sword in his pocket. Somehow Percy manages to make it to a camp for half-bloods, despite the fact that he has to keep killing monsters along the way. But the camp doesn't ring any bells with him. The only thing he can recall from his past is another name: Annabeth.
Hazel is supposed to be dead. When she lived before, she didn't do a very good job of it. Sure, she was an obedient daughter, even when her mother was possessed by greed. But that was the problem — when the Voice took over her mother and commanded Hazel to use her "gift" for an evil purpose, Hazel couldn't say no. Now because of her mistake, the future of the world is at risk. Hazel wished she could ride away from it all on the stallion that appears in her dreams.
Frank is a klutz. His grandmother says he is descended from heroes and can be anything he wants to be, but he doesn't see it. He doesn't even know who his father is. He keeps hoping Apollo will claim him, because the only thing he is good at is archery — although not good enough to win camp war games. His bulky physique makes him feel like an ox, especially infront of Hazel, his closest friend at camp. He trusts her completely — enough to share the secret he holds close to his heart.
Beginning at the "other" camp for half-bloods and extending as far as the land beyond the gods, this breathtaking second installment of the Heroes of Olympus series introduces new demigods, revives fearsome monsters, and features other remarkable creatures, all destined to play a part in the Prophesy of Seven.
Book Three: The Mark of Athena
In The Son of Neptune, Percy, Hazel, and Frank met in Camp Jupiter, the Roman equivalent of Camp Half-blood, 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?
The Greek and Roman demigods will have to cooperate in order to defeat the giants released by the Earth Mother, Gaea. Then they will have to sail together to the ancient land—Greece itself—to find the Doors of Death. What exactly are the Doors of Death? Much of the prophecy remains a mystery...
With old friends and new friends joining forces, a marvelous ship, fearsome foes, and an exotic setting, The Mark of Athena promises to be another unforgettable adventure by master storyteller Rick Riordan.
