Beware the Metal Children — John Peel

Welcome to the seventh grade...again. And again.Fitting in at a new school is tough for any kid. But what if you were a robot? Roger is one of the new children—sophisticated androids created to act and talk and think just like normal kids. Only these kids are machines. A mysterious toxic plague has infected the human population, and the only way to have children is to manufacture them. But machines don't grow up like normal children. They can't grow. They just keep repeating the same year over and over again. At some point Roger's owners—er, parents—will replace him with an older Roger. The problem?Roger doesn't want to be replaced.
