Rick Riordan

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 Olympians: 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.
