At least working at the Middle Rapids Library ain’t so bad. It’s one of those fancy Carnegie libraries with brass chandeliers and porcelain tile work and stained-glass windows — all misplaced decadence for this rust-belt town. It’s pretty much a gothic castle complete with ghosts, labyrinthine hallways, black walnut paneled doors, dusty portraits of old, rich dead men no one wants to look at, and, most mysteriously of all, a turret housing the town’s large, defunct clock.
