The Last Olympian

Rick Riordan
The long-awaited prophecy surrounding Percy Jackson's sixteenth birthday unfolds as he leads an army of young demigods to stop Kronos in his advance on New York ...
This is the final book in the Percy Jackson and the Olympians series. Percy must go and stop Kronos before he and the other Titans destroy Mount Olympus. Percy goes to Camp Half-Blood to hear the Great Prophecy about him reaching his 16th birthday, and what he hears terrifies him. This is a thrilling final installment of the series and I recommend this to anyone above 4th grade.
