The Absolute Value of -1 — Steve Brezenoff

Noah, Lily, and Simon have been a trio forever. But as they enter high school, their relationships shift and their world starts to fall apart. Privately, each is dealing with a family crisis -- divorce, abuse, and a parent's illness. Yet, as they try to escape the pain and reach out for the connections they once counted on, they slip -- like soap in a shower. Noah's got it bad for Lily, but he knows too well that Lily sees only Simon. Simon is indifferent, suddenly inscrutable to friends. All stand alone in their heartache and grief.
