Book Spine Traverse

Swinging down from the lamp was just the warm-up! I launched straight across the gap onto the top shelf of the nearby bookcase. Landing with both boots skidding along polished oak, I found myself facing a giant obstacle course of hardcovers. One thick encyclopedia was leaning at a sketchy forty-five-degree angle over an open mechanical alarm clock. Naturally, I didn't walk around. I scrambled up the sloped spine, crouched right on the narrow top edge, and peered directly into the clock's exposed brass cogs ticking below. Pure mechanical perfection!
