A Palestinian and an Israeli, both bereaved of their children by horrific violence, try to turn their personal tragedies into a force for peace in the seventh novel by National Book Award winner Colum McCann. Divided into 1,001 chapters, some of which are composed of photographs, a single line of text, or a blank page, Apeirogon (which denotes a shape with an infinite number of sides) apparently conducts literary experiments in the service of grief and humanity.
