What terrible secret does Dr. Sharp hide behind his shiny smile? Eleven-year-old Jase and his quirky, new friend, Braxton, discover there may be very good reason to fear their dentist.

("Deadly Dr. Sharp") and his assistant, Alexis, have kidnapped two of their patients and brainwashed the kids' parents into thinking their children have gone to "Colorado." But if the missing middle-schoolers aren't away in some other state, where could they possibly be?
