Regret filled my heart as I snuck a look down. I imagined my grip slipping off the bookshelf. My body dropping 10 stories and splatting on the ground. Perhaps no one would ever find me. I breathed out slowly and turned my focus back to putting one hand above the other, slowly reaching for an ever higher shelf.

A few final heaves later and I was at the top. I received my reward: confirmation that I was screwed. The library went on forever.
