The girl he used to know / Tracey Garvis Graves.

Annika (rhymes with Monica) Rose is an English major at the University of Illinois. Anxious in social situations where she finds most people's behavior confusing, she'd rather be surrounded by the order and discipline of books or the quiet solitude of playing chess.

Annika Rose feels lost in social situations, saying the wrong thing or acting the wrong way; she just can't read people. Working at the Harold Washington Library, she prefers the quiet solitude of books or playing chess to being around others... apart from Jonathan. She liked being around him, but she hasn't seen him for ten years. Jonathan Hoffman is now a Wall Street whiz, recovering from a divorce and seeking a fresh start. When fate reunites them in Chicago, will their second chance end before it truly begins? -- adapted from jacket.
