Olive Kitteridge is the kind of woman you would duck across the street to avoid meeting. She’s abrasive as sandpaper rubbed across a scab and unapologetically rude. Now retired, she taught seventh-grade math in the small Maine town of Crosby for years, earning a reputation as the mean teacher who leaves her students flustered and trembling. She is loud, unnerving, tart-tongued, and completely unforgettable.
