The Lost Hero:

Jason has a problem. He doesn't remember anything before waking up on a school bus holding hands with a girl. Apparently she's his girlfriend Piper, his best friend is a kid named Leo, and they're all students in the Wilderness School, a boarding school for "bad kids." What he did to end up here, Jason has no idea-except that everything seems very wrong.

Piper has a secret. Her father has been missing for three days, and her vivid nightmares reveal that he's in terrible danger. Now her boyfriend doesn't recognize her, and when a freak storm and strange creatures attack during a school field trip, she, Jason, and Leo are whisked away to someplace called Camp Half-Blood. What is going on?

Leo has a way with tools. His new cabin at Camp Half-Blood is filled with them. Seriously, the place beats Wilderness School hands down, with its weapons training, monsters, and fine-looking girls. What's troubling is the curse everyone keeps talking about, and that a camper's gone missing. Weirdest of all, his bunkmates insist they are all-including Leo-related to a god.

Rick Riordan, the best-selling author of the Percy Jackson series, pumps up the action and suspense in The Lost Hero, the first book in The Heroes of Olympus series. Fans of demi-gods, prophesies, and quests will be left breathless--and panting for Book Two.

The Son of Neptune:

Percy is confused. When he awoke after 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. Somehow Percy managed to make it to the camp for half-bloods, despite the fact that he had to continually kill monsters that, annoyingly, would not stay dead. But the camp doesn't ring any bells with him.

Hazel is supposed to be dead. When she lived before, she didn't do a very good job of it. 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.

Frank is a klutz. His grandmother claims he is descended from ancient heroes, but 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. His big and bulky physique makes him feel like a clumsy ox, especially in front of Hazel, his closest friend at camp. He trusts her completely-enough, even, to share the secret he holds close to his heart.

Beginning at the "other" camp for half-bloods and extending as far north as the land beyond the gods, this breathtaking second installment in the Heroes of Olympus series introduces new demigods, revives fearsome monsters, and features other remarkable creatures, all of whom are destined to play a part in the most important quest of all: the Prophecy of Seven.

The 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?

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 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 is be another unforgettable adventure by master storyteller Rick Riordan.

The House of Hades:

At the conclusion of The Mark of Athena, Annabeth and Percy tumble into a pit leading straight to the Underworld. The other five demigods have to put aside their grief and follow Percy's instructions to find the mortal side of the Doors of Death. If they can fight their way through Gaea's forces, and Percy and Annabeth can survive the House of Hades, then the Seven will be able to seal the Doors from both sides and prevent the giants from raising Gaea. But, Leo wonders, if the Doors are sealed, how will Percy and Annabeth be able to escape?

They have no choice. If the demigods don't succeed, Gaea's armies will never die. They have no time. In about a month, the Romans will march on Camp Half-Blood. The stakes are higher than ever in this adventure that dives into the depths of Tartarus.

This paperback edition will include a never-before-seen short story, "The Crown of Ptolemy," in which Percy and Annabeth fight alongside Carter and Sadie Kane, and more bonus content!

The Blood of Olympus:

Though the Greek and Roman crewmembers 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. They must be stopped before the Feast of Spes, when Gaea plans to have two demigods sacrificed in Athens. She needs their blood-the blood of Olympus-in order to wake.

The demigods are having more frequent visions of a terrible battle at Camp Half-Blood. The Roman legion from Camp Jupiter, led by Octavian, is almost within striking distance. Though it is tempting to take the Athena Parthenos to Athens to use as a secret weapon, the friends know that the huge statue belongs back on Long Island, where it might be able to stop a war between the two camps.

The Athena Parthenos will go west; the Argo II will go east. 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.
