Book excerpt: The moon is under threat of a nuclear meltdown due to a space station malfunction. Complicating things is the presence of pleurinium, a magnetic material that makes humans instantly, seriously ill--well, all humans who are 14 years old and up. Mickey Price is an orphan in Orlando; Trace Daniels is a go-kart champion in Nevada; Jonah Jones is a budding scientist in Illinois. They don't know each other, but they are all being watched and studied by men in white shirts, thin black ties, and distinctive gold-colored sunglasses. The three kids are invited to a NASA camp, but this camp isn't for summer fun. It's a training camp for a mission full of dangers that will test each of them to the maximum, but it's also an adventure full of thrills, fun, and some unexpected companions, not all of whom are human.
