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...
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.
This time, we're under attack, and I need to get my hands on the Golden Fleece or we'll be invaded by monsters. Big ones.
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.
