From the back cover:
You are crossing America on your bicycle. . .
When you stop to explore and old mining town. Soon you discover that Silverlode has been invaded by a terrible, bubbling black slime that makes animals howl and people hiss and attack each other in the night. You have no choice but to stay and help solve the mystery!
But whether you find yourself trapped in a river of oozing black evil in your own hotel room, running for your life from a hideous manlike monster, walking a narrow path over a pit of rattlesnakes, imprisoned as a sacrifice for a mad doctor's experiments, battling billions of attacking insects, or defying the eerie powers of the yellow-eyed people- never fear! If you make the right choice, you might also win a million dollars!
So get ready to plunge into adventure. And if you get caught in the black slime, just go back to the beginning and start again.
THIS ADVENTURE BELONGS TO YOU!
Welcome to the world of Which Way books- Where YOU make things happen.
