OLD ENEMIES AWAKEN AS CAMP HALF-BLOOD'S NEW ARRIVALS PREPARE FOR WAR

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?

And don't miss the trio's next adventure in Percy Jackson and the Olympians: Wrath of the Triple Goddess, coming soon!

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 . . .

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.
