How do you punish an immortal?

By making him human.

After angering his father Zeus, the god Apollo is cast down from Olympus. Weak and disoriented, he lands in New York City as a regular teenage boy.

Now, without his godly powers, the four-thousand-year-old deity must learn to survive in the modern world until he can somehow find a way to regain Zeus's favour.

But Apollo has many enemies - gods, monsters and mortals who would love to see the former Olympian permanently destroyed. Apollo needs help, and he can think of only one place to go . . . an enclave of modern demigods known as Camp Half-Blood.

About the Author
Rick Riordan is a teacher and a writer, and has won many awards for his mystery novels for adults. He says that the idea for Percy Jackson and the Lightning Thief first came to him while he was teaching Greek mythology at middle school in San Francisco. But rumour has it that Camp Half Blood actually exists, and Rick spends his summers there recording the adventures of young demigods. Some believe that, to avoid a mass panic among the mortal population, he was forced to swear on the River Styx to present Percy Jackson's story as fiction. Rick lives in Texas (apart from his summers on Half Blood Hill) with his wife and two sons.
