Though the Greek and Roman crew members 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.

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...

He was a God once. Until he was cast out his father, Zeus. Now, he's an awkward teenager. Called Lester.

The only way out is a series of scary and dangerous trials, of course. For his third trial, Apollo must journey through the Labyrinth to free an Oracle who only speaks in puzzles. Then, defeat the most vicious of three very vicious Roman Emperors. (All without the use of his godly powers.)

It looks like he will need all the help he can get - from some new and old friends.

Book 3 in the Trials of Apollo series.

Mysterious incidents are wreaking havoc throughout Camp Jupiter. And if the Romans don't find out who-or what-is behind the episodes soon, the Twelfth Legion could implode. So things are looking pretty serious. 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. To find out the truth, see through Claudia's eyes the crime scenes, and watch as the bizarre events unfold. Be by her side when she discovers a secret so ancient not even the lares know about. A secret that holds the key to Camp Jupiter's safety...

Percy Jackson has saved the world multiple times - battling monsters, Titans, even giants - but these days the modern-day son of Poseidon is hoping for a regular final year at school. Too bad the Greek gods have other plans, and three new quests for Percy to complete. First up: the cupbearer of the gods, Ganymede, is missing his golden chalice. Not only is this embarrassing (why do the gods keep losing their magical items?), it's also potentially disastrous. One sip from the cup will turn any mortal into a powerful god. And the old gods do not take kindly to newbies. Can Percy and his friends Annabeth and Grover find the chalice before it falls into the wrong hands? And even if they do, will they be able to resist its awesome power. . .?

Ana Dakkar is a freshman at Harding-Pencroft Academy, a five-year high school that graduates the best marine scientists, naval warriors, navigators and underwater explorers in the world.

Ana's parents died while on a scientific expedition two years ago, and the only family's she's got left is her older brother, Dev, also a student at HP. Ana's freshman year culminates with the class' weekend trial at sea, the details of which have been kept secret.

She only hopes she has what it'll take to succeed. All her worries are blown out of the water when, on the bus ride to the ship, Ana and her schoolmates witness a terrible tragedy that will change the trajectory of their lives.

The stakes have never been higher. If Percy Jackson and Annabeth fail in their quest, there'll be hell on Earth. Literally.

Wandering the deadly realm of Tartarus, every step leads them further into danger. And, if by some miracle they do make it to the Doors of Death, there's a legion of bloodthirsty monsters waiting for them.

Meanwhile, Hazel and the crew of the Argo II have a choice: to stop a war or save their friends. Whichever road they take one thing is certain - in the Underworld, evil is inescapable.

Book 4 in the House of Olympus series.

When Jason, Piper and Leo crash land at Camp Half-Blood, they have no idea what to expect. Apparently this is the only safe place for children of the Greek Gods - despite the monsters roaming the woods and demigods practising archery with flaming arrows and explosives.

But rumours of a terrible curse - and a missing hero - are flying around camp.
It seems Jason, Piper and Leo are the chosen ones to embark on a terrifying new quest, which they must complete by the winter solstice. In just four days time.

Can the trio succeed on this deadly mission - and what must they sacrifice in order to survive?

Book1 in the Heroes of Olympus series.

Annabeth felt as if someone had draped a cold washcloth across her neck. She heard that whispering laughter again, as if the presence had followed her from the ship.

She looked up at the Argo II. Its massive bronze hull glittered in the sunlight. Part of her wanted to kidnap Percy right now, get on board and get out of here while they still could.

She couldn't shake the feeling that something was about to go terribly wrong. She couldn't risk losing Percy again.

Book 3 in the Heroes of Olympus series.

Time is running out as war between the Olympians and the evil Titan lord Kronos draws near. Even the safe haven of Camp Half Blood grows more vulnerable by the minute as Kronos's army prepares to invade its once impenetrable borders. To stop them, Percy and his demigod friends will set out on a quest through the Labyrinth - a sprawling underground world with stunning surprises at every turn.

Who could tell the true stories of the gods and goddesses of Olympus better than modern-day demigod Percy Jackson?

In this action-packed tour of Greek mythology, Percy gives his hilarious personal views on the feuds, fights and love affairs of the Olympians.

Want to know how Zeus came to be top god? How many times Kronos ate one of his own kids? How Athena literally burst out of another god's head?

It's all here in black and white...

In this gripping follow-up to Percy Jackson and the Greek Gods, demigod Percy Jackson tells the stories of twelve of the original Greek heroes in all their gory, bloodthirsty glory.

The greatest monster of all, the storm giant Typhon, is on the loose, wreaking havoc and destruction across the U S - while Kronos's army lays siege to Manhattan. Soon Percy Jackson must make the hardest choice of his life - a choice that will save or destroy the world.

I was just a normal kid, going to school, playing basketball, skateboarding. The usual. Until I accidentally vaporized my maths teacher. Now I spend my time battling monsters and generally trying to stay alive.

This is the one where Zeus, God of the Sky, thinks I've stolen his lightning bolt - and making Zeus angry is a very bad idea..

I look like a normal kid. Only there's a difference. Poseidon, God of the Sea is my dad. Which sounds cool, but actually means there is usually someone (or something), somewhere, trying to kill me.

Now I live at Camp Half-Blood, with other kids like me, but instead of toasting marshmallows and singing campfire songs, we battle giant cannibals at dodgeball. This time, we're under attack and I need to get my hands on the Golden Fleece or we'll be invaded by monsters. Big ones.

It's the last Friday before the winter holidays but Percy Jackson isn't at school: he's battling the fearsome Manticore (half human, half lion), which in itself isn't ideal . . . but with Annabeth missing and the goddess of the hunt held captive, things get a whole lot more serious . . .

Demigod Percy Jackson has a small problem – he can’t remember anything. All he knows is that he must get away from these terrifying snake-haired women before they vaporize him.

Soon after, Percy finds himself at Camp Jupiter – a haven for demigods like him. It should ring a bell... But something isn’t right. Still, there’s only one thing Percy can remember from his past. The name Annabeth.

But Percy's questing days aren't over and now he, and his new friends, must face their deadliest trial ever... rescuing the literal god of Death.

No one ever said being a demigod was easy!

Book 2 in the Heroes of Olympus series.

The battle for Camp Jupiter is over. New Rome is safe. Tarquin and his army of the undead have been defeated. Somehow Apollo has made it out alive, with a little bit of help from the Hunters of Artemis. But though the battle may have been won, the war is far from over. Now Apollo and Meg must get ready for the final - and, let's face it, probably fatal - adventure. They must face the last emperor, the terrifying Nero, and destroy him once and for all. Can Apollo find his godly form again? Will Meg be able to face up to her troubled past? Destiny awaits...
