From the National Book Award-winning and bestselling author of Let the Great World Spin comes an epic novel rooted in the real-life friendship between two men united by loss. Colum McCann's most ambitious work to date, Apeirogon--named for a shape with a countably infinite number of sides--is a tour de force concerning friendship, love, loss, and belonging. Bassam Aramin is Palestinian. Rami Elhanan is Israeli. They inhabit a world of conflict that colors every aspect of their daily lives, from the roads they are allowed to drive on, to the schools their daughters, Abir and Smadar, each attend, to the checkpoints, both physical and emotional, they must negotiate. Their worlds shift irreparably after ten-year-old Abir is killed by a rubber bullet and thirteen-year-old Smadar becomes the victim of suicide bombers. When Bassam and Rami learn of each other's stories, they recognize the loss that connects them and they attempt to use their grief as a weapon for peace. McCann crafts Apeirogon out of a universe of fictional and nonfictional material. He crosses centuries and continents, stitching together time, art, history, nature, and politics in a tale both heartbreaking and hopeful. Musical, cinematic, muscular, delicate, and soaring, Apeirogon is a novel for our time.
