EVER since the gods of Ancient Egypt were unleashed on the modern world, Carter Kane and his sister, Sadie, have been in big trouble. As descendants of the magical House of Life, they command certain powers. But now a terrifying enemy – Apophis, the giant snake of chaos – is rising. If Carter and Sadie don't destroy him, the world will end in five days' time. And in order to battle the forces of chaos, they must revive the sun god Ra – a feat no magician has ever achieved. Because first they must search the world for the three sections of the Book of Ra, then they have to learn how to chant its spells . . . Can the Kanes destroy Apophis before he swallows the sun and plunges the earth into darkness . . . forever? 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.
