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.

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.

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 . . .

ONE PROPHECY. TWO DEMIGODS. A HEROIC QUEST. Nico di Angelo is pretty familiar with the realms of death being the son of Hades and all. So when a desperate voice starts plaguing his dreams Nico is convinced it's coming from the Underworld and belongs to an old friend - a reformed Titan called Bob. Then an ominous prophecy leaves Nico in no doubt - Bob needs his help and Nico must rescue him.

Of course Nico's boyfriend Will Solace the son of Apollo (the god of light) insists on joining the quest too. But can will even survive in the darkest part of the world? And what does the prophecy mean when it says that Nico will have to leave something of equal value behind? As Nico faces demons both internal and external his relationship with Will is tested to its very core. Can love find its way even through the depths of hell?

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...
