Lionel Shriver, We need to talk about Kevin

 In a series of letters addressed to her husband, mother tries to understand why her son, 15-year-old Kevin, murdered seven of his fellow classmates, a cafeteria worker and his English teacher in a Columbine-style school massacre.

Incredibly well written, drawing the reader into the mother’s reflections on the possible reasons for Kevin’s actions, moving seamlessly between time periods, and subtly instilling doubt into the reader’s mind as to the reliability of the narrator’s perspective.
