The Hunters of Jundagai. Keys to the Dimensions Book 6

Cy Yancey dreamt of being a big game hunter adventuring in Africa. Little did he know that stepping into an alleyway outside his rifle club would lead him to the most important hunt in his life, a hunt that would take Cy much farther than Africa, a hunt through the worlds of the Dimensions, seeking, of all things, Earth! For Yancey, in trying to grab a cab, ends up hitching a ride with Porteurs Zelda and Jorine - escapees from the power of the mysterious Contessa.
Fleeing with them, Yancey is bounced from one Dimension to another until he arrives on Jundagai, planet of the Hunters. On Jundagai lies the answer to Yancey's dreams. The Hunt reigns supreme, though often one is not sure what the quarry is. But Jundagai holds still a greater attraction. Jundagai, Yancey's prison, holds the key to home. Yancey has only to find the right lock before death finds him.
