Most adventures open up. This one closes in. In the Cave, the tight squeeze between two cushions, finding what's hiding in the dark- these aren't obstacles to the adventure, they ARE the adventure. Woven through it are the stories of a deputy sheriff who found a spider so strange that scientists had to invent an entire new family to describe it, a cave that humans have been entering by torchlight for five thousand years, and a time when the whole world came to the rescue.
