Synopsis (from Amazon.com): 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.
Age: 9, but I would like to add that parents may want to read the books with their younger children and make it clear that the Greek gods aren’t real.
Inappropriate content: Very little.
My thoughts: This is my absolute favorite out of all the Percy Jackson books. Prophecies + gods + heroes + Titans = AMAZING
