The Lost Compass (Fog Diver)

Chess and his crew - Hazel, Swedish, Loretta, and Bea - may have escaped the slums, but they cannot escape the Fog that threatens to swallow the entire mountaintop city of Port Oro. Only one thing can stop the Fog: an ancient machine known as the Compass. And only one person can find it: Chess. With the help of his crew, Chess faces dangerous encounters and deadly driftsharks to unearth the hidden instrument. It’s a race against time to save this sanctuary in the sky.

With adventure at every turn, peril behind every corner, and a few determined slum kids who must save the day, Joel Ross presents a fantastic world in this fast-paced follow-up to The Fog Diver.
