Capstone Global Library Ltd Ooze Control - Express Edition

After school, a boy boards an odd-looking bus. Inside, the floor, the seats and even the ceiling are covered with used up chewing gum. Soon, the sticky gum grows thicker, climbs higher, comes alive . . . and the bus windows will not open! Can the boy escape before the ooze takes control? Autorid: Michael Dahl, Euan Cook
