The explosive third part in Rick Riordan's number-one series - set in the world of Percy Jackson - now available as an unabridged audio download. One fatal prophecy. Seven brave demigods. A quest to find - and close - the door of death.

Penguin presents this downloadable audiobook edition, of the number one, bestselling title in this new spin-off series from Percy Jackson creator, Rick Riordan. 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.

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.

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.

Normally when you turn 16 you get a really cool present. But, being sixteen and the son of Poseidon can never be that simple. So instead, I get a prophecy that says the fate of the entire world on my shoulders. Great. On top of that, Kronos, Lord of the Titans, is attacking New York City and the dreaded monster Typhon is heading our way. So, it's me and forty of my demi-god friends versus untold evil. Happy birthday to me!

My life could have been the same as an ordinary teenager. Except my dad is Poseidon, and I live in a camp full of half Gods and mythical creatures. So instead, my days are spent combatting half-lion half-humans and trying to live a somewhat normal life. But normalcy has just gone out the window. My friend Annabeth is missing, a Goddess is in chains, and only five of us can join the quest to save the day. Oh and guess what. The Oracle has predicted that not all of us will survive....

Penguin presents the unabridged, downloadable audiobook edition of The Hidden Oracle: The Trials of Apollo, Book One, by Rick Riordan, read by Robbie Daymond. How do you punish an immortal? By making him human. After angering his father, Zeus, the god Apollo is cast down from Olympus. Weak and disorientated, he lands in New York City as a regular teenage boy.

The former God Apollo is having a pretty rough time of it. Well, for one thing, he's called Lester. But being an awkward mortal teenager is the least of his worries. Though he and his friends (some of them) have emerged from the Burning Maze, they still have a triumvirate to defeat, oracles to rescue and prophecies to decipher so that the world may be saved, and Lester can become Apollo once again. But right now, Caligula is sailing to San Francisco to deal with Camp Jupiter personally, and they have to get their first. Or risk its destruction.....

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 Camp Half-Blood is a bit different to most summer camps. Instead of toasting marshmallows and singing campfire songs, we battle giant cannibals at dodgeball.

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.... 

Penguin presents the unabridged, downloadable, audiobook edition of Percy Jackson and the Greek Gods by Rick Riordan, read by Jesse Bernstein. 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?

The unabridged, downloadable audiobook edition of The Kane Chronicles: The Throne of Fire, read by Joseph May and Jane Collingwood. Ever since the gods of Ancient Egypt were unleashed on the modern world, Carter Kane and his sister, Sadie, have been in big trouble. As descendants of the magical House of Life, they command certain powers.

The god Apollo, cast down to earth and trapped in the form of a gawky teenage boy as punishment, must set off on the second of his harrowing (and hilarious) trials. He and his companions seek the ancient oracles - restoring them is the only way for Apollo to reclaim his place on Mount Olympus - but this is easier said than done. Somewhere in the American Midwest is a haunted cave that may hold answers for Apollo in his quest to become a god again...if it doesn't kill him or drive him insane first.
