How do you handle an encounter with Medusa on the New Jersey interstate? What's the best way to take down a minotaur? Become an expert on everything in Percy's world with this must-have guide to the Percy Jackson and the Olympians series. Complete with interviews, puzzles, games, and original short stories by Rick Riordan.

In response to an awful camp orientation video created by the god Apollo, Percy Jackson and other residents of Camp Half-Blood answer such questions as "what is this place?" and "do I get to keep the T-shirt?" Newbies can check out the section on the divine cabins, learn about magical landmarks, and consult the chapter on training arenas. But Camp Half-Blood Confidential explores much more than just the buildings and grounds.

Who cut off Medusa's head? Who was raised by a she-bear? Who tamed Pegasus? And whatever happened to that Golden Fleece? It takes a demigod to know the answers, and Percy Jackson can fill you in on all the daring deeds of Perseus, Atalanta, Bellerophon, and the rest of the major Greek heroes.

It's the February after Gaea's defeat, and mysterious incidents are wreaking havoc throughout Camp Jupiter. If the Romans don't figure out who - or what - is behind the episodes soon, the Twelfth Legion could implode. Suspicion falls on Claudia, the Fourth Cohort's newest probatio. After all, the mischief started shortly after she stumbled into camp. Plus, she's a daughter of Mercury, the god of thieves and tricksters.

"A publisher in New York asked me to write down what I know about the Greek gods, and I was like, 'Can we do this anonymously?' Because I don't need the Olympians mad at me again. But if it helps you to know your Greek gods, and survive an encounter with them if they ever show up in your face, then I guess writing all this down will be my good deed for the week." So begins Percy Jackson's Greek Gods, in which the son of Poseidon adds his own magic - and sarcastic asides - to the classics.

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 the 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?

Lester's demigod friends at Camp Jupiter just helped him survive attacks from bloodthirsty ghouls, an evil Roman king and his army of the undead, and the lethal emperors Caligula and Commodus. Now the former god and his demigod master Meg must follow a prophecy uncovered by Ella the harpy. Lester's final challenge will be at the Tower of Nero, back in New York.

It's not easy being Apollo, especially when you've been turned into a human and banished from Olympus. On his path to restoring five ancient oracles and reclaiming his godly powers, Apollo (a.k.a. Lester Papadopoulos) has faced both triumphs and tragedies. Now, his journey takes him to Camp Jupiter in the San Francisco Bay Area, where the Roman demigods are preparing for a desperate last stand against the evil Triumvirate of Roman emperors. Hazel, Reyna, Frank, Tyson, Ella, and many other old friends will need Apollo's aid to survive the onslaught.

Zeus has punished his son Apollo - god of the sun, music, archery, poetry, and more - by casting him down to earth in the form of a gawky, acne-covered 16-year-old mortal named Lester. The only way Apollo can reclaim his rightful place on Mount Olympus is by restoring several Oracles that have gone dark. What is affecting the Oracles, and how can Apollo/Lester do anything about them without his powers?

In The Lost Hero, three demigods named Jason, Piper, and Leo made their first visit to Camp Half-Blood, where they inherited a quest.

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 figurehead, Leo’s fantastical creation doesn’t appear friendly. Annabeth hopes that the sight of their praetor Jason on deck will reassure the Romans.

After angering his father, Zeus, the god Apollo is cast down from Olympus. Weak and disoriented, he lands in New York City as a regular teenage boy. Now, without his godly powers, the 4,000-year-old deity must learn to survive in the modern world until he can somehow find a way to regain Zeus' favor. But Apollo has many enemies - gods, monsters, and mortals who would love to see the former Olympian permanently destroyed.

After saving Olympus from the evil Titan lord, Kronos, Percy and friends have rebuilt their beloved Camp Half-Blood, where the next generation of demigods must now prepare for a chilling prophecy of their own.... In a brand-new series from blockbuster best-selling author Rick Riordan, fans return to the world of Camp Half-Blood. Here, a new group of heroes will inherit a quest. But to survive the journey, they'll need the help of some familiar demigods.
