All year the half-bloods have been preparing for battle
against the Titans, knowing the odds of victory are grim.
Kronos's army is stronger than ever, and with every god and
half-blood he recruits, the evil Titan's power only grows.
While the Olympians struggle to contain the rampaging
monster Typhon, Kronos begins his advance on New York City,
where Mount Olympus stands virtually unguarded. Now it's up
to Percy Jackson and an army of young demigods to stop the
Lord of Time.
In this momentous final book in the New York Times
best-selling Percy Jackson and the Olympians series, the
long-awaited prophecy surrounding Percy's sixteenth birthday
unfolds. And as the battle for Western civilization rages on
the streets of Manhattan, Percy faces a terrifying suspicion
that he may be fighting against his own fate.
