"The Titan's Curse" is book 3 in the "Percy Jackson and the Olympians" series. If you missed my reviews on the first two books you kind find them here.
In "The Titan's Curse" Percy finds himself heading off to try and rescue two new half-bloods that his friend Grover has found. Soon their setting off on yet another quest, this time in the company of a Hunter, and it's the most challenging one yet.
Before they set off on their quest the oracle tells them:
"Five shall go west to the goddess in chains,
one shall be lost in the land without rain,
The bane of Olympus shows the trail,
Campers and hunters combined prevail,
The Titan's curse must one withstand,
And one shall perish by a parent's hand."
A grim sign to start out under, but start out they do, and you'll have a lot of fun finding out what this omen means!
