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!

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.

"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.

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.
