I would highly suggest reading the Percy Jackson and the Olympians series before picking up a single book from this series. Here's the link if you want to check them out. :)
Back of Book:
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.

Back of Book:
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.

Back of Book:
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 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 command: 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.

Back of Book:
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?
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.

Back of Book:
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.

Back of Book:
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. He explains how the world was created, then gives readers his personal take on a who's who of ancients, from Apollo to Zeus. Percy does not hold back. "If you like horror shows, blood baths, lying, stealing, backstabbing, and cannibalism, then read on, because it definitely was a Golden Age for all that."

Who cut off Medusa's head? Who was raised by a she-bear? Who tamed Pegasus? It takes a demigod to know, and Percy Jackson can fill you in on the all the daring deeds of Perseus, Atalanta, Bellerophon, and the rest of the major Greek heroes. Told in the funny, irreverent style readers have come to expect from Percy,
(I've had some bad experiences in my time, but the heroes I'm going to tell you about were the original old school hard luck cases. They boldly screwed up where no one had screwed up before. . .) and enhanced with vibrant artwork by Caldecott Honoree John Rocco, this story collection will become the new must-have classic for Rick Riordan's legions of devoted fans—and for anyone who needs a hero.
So get your flaming spear. Put on your lion skin cape. Polish your shield and make sure you've got arrows in your quiver. We're going back about four thousand years to decapitate monsters, save some kingdoms, shoot a few gods in the butt, raid the Underworld, and steal loot from evil people.
Then, for dessert, we'll die painful tragic deaths.
Ready? Sweet. Let's do this.
