Being the son of a Greek God, nothing in my life has been straightforward. Or monster-free. And it looks like that's not going to change anytime soon now that my arch enemy Luke wants to invade Camp Half-Blood via an ancient labyrinth.If he succeeds, thousands of bloodthirsty monsters will attack. So it's goodbye sunshine, hello darkness as four of us descend into the terrifying underground and beyond....

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.

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!

I was just a normal kid, I went to school (got expelled a lot, but that wasn't my fault), played sports and hung out with my best friend.Until I accidentally vaporized my maths teacher.Now, I spend my time at Camp Half Blood, battling monsters and generally trying to stay alive.And now that Zeus thinks I've stolen his lightning bolt, staying alive is going to be even harder.

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.

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.

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 figurehead, Leo’s fantastical creation doesn’t appear friendly. Annabeth hopes that the sight of their praetor Jason on deck will reassure the Romans.

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.

"A publisher in New York asked me to write down what I know about the Greek gods, and I was like, 'Can we do this anonymously?' Because I don't need the Olympians mad at me again. But if it helps you to know your Greek gods, and survive an encounter with them if they ever show up in your face, then I guess writing all this down will be my good deed for the week." So begins Percy Jackson's Greek Gods, in which the son of Poseidon adds his own magic - and sarcastic asides - to the classics.

Thor's hammer is missing again. The thunder god has a disturbing habit of misplacing his weapon - the mightiest force in the Nine Worlds. But this time the hammer isn't just lost; it has fallen into enemy hands. If Magnus Chase and his friends can't retrieve the hammer quickly, the mortal worlds will be defenseless against an onslaught of giants. Ragnarok will begin.

Carter and Sadie Kane's dad is a brilliant Egyptologist with a secret plan that goes horribly wrong. An explosion shatters the ancient Rosetta stone and unleashes Set, the evil god of chaos. Set imprisons Dr Kane in a golden coffin and Carter and Sadie must run for their lives. To save their dad, they embark on a terrifying quest from Cairo to Paris to the American Southwest and discover the truth about their family’s connection to the House of Life: an Egyptian temple of magic that has existed for thousands of years.

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.

Young Demigods, Your Destiny Awaits! You must prepare yourself for a difficult future: fighting monsters, adventuring across the globe, and dealing with temperamental Greek and Roman gods. You’ll join your favorite demigods from the Percy Jackson and the Heroes of Olympus series as they face dangerous foes and perilous tasks. What you learn from their experiences could very well save your life!
