Escape! (Library Binding)

Four high school friends sign up for a TV escape-room competition, but they're assigned to a set that's actually a series of rooms. They have twelve hours to find a way out, but the faster they're able to do it, the higher their prize money will be. As the clues get harder and the time ticks by, tensions run high and confrontations occur. Soon the prize money isn't the only reason they're all desperate to escape.
