Demigod Percy Jackson has a small problem - he can't remember anything. All he knows is that he must get away from these terrifying snake-haired women before they vaporize him.

Soon after, Percy finds himself at Camp Jupiter - a haven for demigods like him. It should ring a bell... But something isn't right. Still, there's only one thing Percy can remember from his past. The name Annabeth.

But Percy's questing days aren't over and now he, and his new friends, must face their deadliest trial ever... rescuing the literal god of Death.

No one ever said being a demigod was easy!
