The Adjusters by Andrew Taylor
Welcome to Newton, the perfect town...Where kids get perfect grades...And everyone seems perfectly happy - all the time...Except Newcomer Henry Ward isn't buying it. With a pair of misfit friends, he's determined to expose the dark secrets lurking behind Newton's bright facade. But asking questions about Newton and the corporation that owns it can be dangerous. The doctors in the sinister medical centre on the hill have a procedure called "adjustment" for kids who don't fit in...And Henry and his friends have just gone to the top of the waiting list.
