Percy Jackson and the Titan's Curse

It’s not every day you find yourself in combat with a half-lion, half human. . .
Percy Jackson has a lot on his plate.
A powerful goddess has gone missing. The Greek gods are on the brink of war with the Titans. And there’s the minor threat of a mystery beast that could destroy Mount Olympus forever.
This time, Percy’s going to need help and he’s found two powerful demigods for the job. . .There’s just the small problem of the prophecy. The one that has predicted not all of them will survive.
But when you’re the son of a Greek god, it happens. Right?
