Percy Jackson and the Olympians, Book 5.

For a year, the demigods of Camp Half-Blood have trained for war, knowing they stand little chance against the growing forces of Kronos, the Titan lord of time. With each fallen ally and every ancient power awakened, his army swells and Olympus grows weaker.

As the gods struggle to contain the monstrous Typhon rampaging across the continent, Kronos seizes his moment. New York Cityhome to the modern Mount Olympusstands nearly defenseless. The fate of the world now rests in the hands of Percy Jackson and a ragtag army of young heroes.

But this war is more than just swords and strategy. The long-dreaded prophecy tied to Percys sixteenth birthday is coming true, and with it, a choice that could either save the gods or doom them all.

In The Last Olympian, Rick Riordan delivers a breathtaking finale filled with earth-shattering battles, ancient magic, and the clash of destiny versus free will.
