Just before her last year of school, Hilary watches as a new family moves in next door. It doesn't take long for her best friend Shannon to interrupt her observations and force her to introduce herself. The Mom and Dad are oddly formal. Alex, the little sister is a brat and Ben, the son, is hot with a capital H. Even better, he seems to be a truly great guy. Later that night, Hilary watches as Ben and his father walk across their back yard and then disappear into thin air. She can still hear them talking, but their voices sound distorted and tinny. She huddles in the shadows until they are done unloading weird electrical equipment from the invisible place they disappeared into. School starts and weird things begin to happen. Strange purple lights fill the air, weaving and bobbing over the bog behind their homes as if searching for something. Ben realizes he needs Hilary's help if he wants to escape the aliens after his family. The Hurlingen are on their way to Earth and it's going to take almost everyone they know, to stop these horrible aliens from kidnapping Ben and Alex.
