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.

Percy is confused. When he awoke from his long sleep, he didn't know much more than his name. Somehow he has managed to make it to camp for half-bloods, but it 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. Now, because of a mistake, she made back then, the future of the world is at risk. Hazel wishes she could ride away from it all on a stallion that appears in her dreams.

Frank is a klutz. His grandmother says he is descended from heroes, but he doesn't see it. His bulky physique makes him feel like an ox, especially in front of Hazel, his closest friend. 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 in the Heroes of Olympus series introduces new demigods, revives fearsome monsters, and features other remarkable creatures, all destined to play a part in the Prophecy of Seven.

Annabeth is terrified. Just when she’s about to be reunited with Percy—after six months of being apart, thanks to Hera—it looks like Camp Jupiter is preparing for war. As Annabeth and her friends Jason, Piper, and Leo fly in on the Argo II, she can’t blame the Roman demigods for thinking the ship is a Greek weapon. With its steaming bronze dragon masthead, Leo’s fantastical creation doesn’t appear friendly. Annabeth hopes that the sight of their praetor Jason on deck will reassure the Romans that the visitors from Camp Half-Blood are coming in peace. And that’s only one of her worries. In her pocket Annabeth carries a gift from her mother that came with an unnerving demand: Follow the Mark of Athena. Avenge me. Annabeth already feels weighed down by the prophecy that will send seven demigods on a quest to find—and close— the Doors of Death. What more does Athena want from her? Annabeth’s biggest fear, though, is that Percy might have changed. What if he’s now attached to Roman ways? Does he still need his old friends? As the daughter of the goddess of war and wisdom, Annabeth knows she was born to be a leader, but never again does she want to be without Seaweed Brain by her side. Narrated by four different demigods, The Mark of Athena is an unforgettable journey across land and sea to Rome, where important discoveries, surprising sacrifices, and unspeakable horrors await. Climb aboard the Argo II, if you dare...

The demigod crew of the Argo II is standing at a crossroads. They could return home with the Athena Parthenos statue and try to stop Camp Half-Blood and Camp Jupiter from going to war. Or they could continue on their quest to find the House of Hades, where they might be able to open the Door of Death, rescue their friends Percy and Annabeth from Tartarus (if they have survived), and prevent monsters from being reincarnated in the mortal world. Whichever road they decide to take, they have to hurry, because time is running out. Gaea, the bloodthirsty Earth Mother, has set the date of August 1 for her rise to power. 

Join the demigods of the prophecy as they face their biggest challenges yet in The House of Hades, the hair-raising penultimate book in the best-selling Heroes of Olympus series.

Nico had warned them. Going through the House of Hades would stir the demigods' worst memories. Their ghosts would become restless. Nico may actually become a ghost if he has to shadow-travel with Reyna and Coach Hedge one more time. But that might be better than the alternative: allowing someone else to die, as Hades foretold.

Jason's ghost is his mother, who abandoned him when he was little. He may not know how he is going to prove himself as a leader, but he does know that he will not break promises like she did. He will complete his line of the prophecy: To storm or fire the world must fall.

Renya fears the ghosts of her ancestors, who radiate anger. But she can't allow them to distract her from getting the Athena Parthenos to Camp Half-Blood before war breaks out between the Romans and Greeks. Will she have enough strength to succeed, especially with a deadly hunter on their trial?

Leo fears that his plan won't work, that his friends might interfere. But there is no other way. All of them know that one of the Seven has to die in order to defeat Gaea, the Earth mother.

Piper must learn to give herself over to fear. Only then will she be able to do her part at the end: utter a single word.

Heroes, gods, and monsters all have a role to play in the climatic fulfillment of the prophecy in The Blood of Olympus, the electrifying finale of the bestselling Heroes of Olympus series.

You must prepare yourself for a difficult future: fighting monsters, adventuring across the globe, and dealing with temperamental Greek and Roman gods. In this top-secret collection of four never-before-told stories, character portraits, and interviews, maps, diagrams, and puzzles from Camp Half-Blood  Senior Scribe Rick Riordan, you'll join your favorite demigods from the Percy Jackson and the Heroes of Olympus series as they face dangerous foes and perilous tasks. What you learn from their experiences could very well save your life!

Camp Half-Blood Confidential explores much more than just the buildings and grounds. It includes info that can only be learned from those who live there. For instance, campers do not always co-exist in peace and harmony. The camp is not run with superior efficiency. Prophecies do not flow forth with great regularity. Sprinkled throughout are stories from heroes who have called Camp Half-Blood home or just passed through on their way to places unknown. Chiron himself introduces the book with a brief history of training based on his millennia of experience. And, of course, divine words of wisdom from the god Apollo himself are included, because the demigod authors would prefer not to be struck down by him, thank you very much.
