A rat darts across the opening pages, into a hole, and down a long tunnel, stopping under a hammock. A mole man stretches and wakes up, leading the rat and the reader deeper into the tunnel. What follows is a series of dreamlike sequences, each stranger than the last. In this wordless classic, special emphasis is placed on the power of gesture. Cave-In is an all-ages adventure story, jam-packed with monsters, bats, and all manner of unimaginable underground mystery.
