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.

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....

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....

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!

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.

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!

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.

Trolls, giants and worse monsters are stirring for doomsday. To prevent Ragnarok, Magnus must search the Nine Worlds for a weapon that has been lost for thousands of years.

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.....
