Danny Lopez is new in town. He made a mistake back home in Las Vegas, and now he has landed at an experimental school in Colorado for “tough cases.” At the Cobalt Charter School, everything is scripted—what the teachers say, what the students reply—and no other speaking is allowed. This supercontrolled environment gives kids a second chance to make something of themselves. But with few freedoms, the students become sitting ducks for a killer determined to “clean up” Colorado Springs.
