The Son of Sobek (Percy Jackson & Kane Chronicles Crossover #1)

Carter Kane is investigating rumored sightings of a monster on Long Island when he runs into something else: a mysterious boy named Percy Jackson. And their meeting isn't exactly friendly. . . . Includes a sneak peek chapter from HOUSE OF HADES, Book Four in the Heroes of Olympus series.

The Red Pyramid (Kane Chronicles #1)

Since their mother's death, Carter and Sadie have become near strangers. While Sadie has lived with her grandparents in London, her brother has traveled the world with their father, the brilliant Egyptologist, Dr. Julius Kane.

One night, Dr. Kane brings the siblings together for a "research experiment" at the British Museum, where he hopes to set things right for his family. Instead, he unleashes the Egyptian god Set, who banishes him to oblivion and forces the children to flee for their lives.

Soon, Sadie and Carter discover that the gods of Egypt are waking, and the worst of them —Set— has his sights on the Kanes. To stop him, the siblings embark on a dangerous journey across the globe - a quest that brings them ever closer to the truth about their family and their links to a secret order that has existed since the time of the pharaohs.

The Throne of Fire (Kane Chronicles #2)

Ever since the gods of Ancient Egypt were unleashed in the modern world, Carter Kane and his sister Sadie have been in trouble. As descendants of the House of Life, the Kanes have some powers at their command, but the devious gods haven't given them much time to master their skills at Brooklyn House, which has become a training ground for young magicians.

And now their most threatening enemy yet - the chaos snake Apophis - is rising. If they don't prevent him from breaking free in a few days' time, the world will come to an end. In other words, it's a typical week for the Kane family.

To have any chance of battling the Forces of Chaos, the Kanes must revive the sun god Ra. But that would be a feat more powerful than any magician has ever accomplished.

First they have to search the world for the three sections of the Book of Ra, then they have to learn how to chant its spells. Oh, and did we mention that no one knows where Ra is exactly?

Narrated in two different wisecracking voices, featuring a large cast of new and unforgettable characters, and with adventures spanning the globe, this second installment in the Kane Chronicles is nothing short of a thrill ride.

The Serpent's Shadow (Kane Chronicles #3)

He's b-a-a-ack! Despite their best efforts, Carter and Sadie Kane can't seem to keep Apophis, the chaos snake, down. Now Apophis is threatening to plunge the world into eternal darkness, and the Kanes are faced with the impossible task of having to destroy him once and for all. Unfortunately, the magicians of the House of Life are on the brink of civil war, the gods are divided, and the young initiates of Brooklyn House stand almost alone against the forces of chaos. The Kanes' only hope is an ancient spell that might turn the serpent's own shadow into a weapon, but the magic has been lost for a millennia. To find the answer they need, the Kanes must rely on the murderous ghost of a powerful magician who might be able to lead them to the serpent's shadow . . . or might lead them to their deaths in the depths of the underworld. Nothing less than the mortal world is at stake when the Kane family fulfills its destiny in this thrilling conclusion to the Kane Chronicles.

The Lost Hero (The Heroes of Olympus #1)

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. Piper doesn’t understand her dream, or why her boyfriend suddenly doesn’t recognize her. When a freak storm hits, 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. Weirdest of all, his bunkmates insist that each of them—including Leo—is related to a god.

The Son of Neptune (The Heroes of Olympus #2)

Seven half-bloods shall answer the call,

To storm or fire the world must fall.

An oath to keep with a final breath,

And foes bear arms to the Doors of Death.

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.

The Mark of Athena (The Heroes of Olympus #3)

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....
