Have you ever wondered what it would be like to bump into your first love years later as grown adults? To see the person they become — Did they marry and have kids? Have they left you completely in the past? That's what happens to the lead protagonists in Tracey Garvis Graves's The Girl He Used to Know. Annika and Jonathan met as students at the University of Illinois, and their romance was a whirlwind until it all came crashing down. Still in Chicago a decade later, they run into each other out of chance. Is it destiny or pure coincidence?
