We need to talk about Kevin
(Book)

Eva never really wanted to be a mother and certainly not the mother of the unlovable boy who murdered seven of his fellow high school students, a cafeteria worker, and a much-adored teacher who tried to befriend him, all two days before his sixteenth birthday. Now, two years later, it is time for her to come to terms with marriage, career, family, parenthood, and Kevin's horrific rampage in a series of startlingly direct correspondences with her estranged husband, Franklyn.
