The Prime of Miss Jean Brodie

This oft-praised Scottish classic has been on my TBR for ages (and is short enough I could finish it in an afternoon should I make up my mind to do so!) Set in 1930s Edinburgh, the story centers on a nonconformist school teacher who is dismissed after she is betrayed by one of her students. The Guardian calls this "a sublime miracle of wit and brevity," and ranks it #79 on their all-time list of best novels.
