In 1986, a child disappears. Nearly forty years later, a tip-line rings. It's been almost four decades since Edie Marshall's little brother, Charlie, vanished on his walk home from day camp. After the case went cold, Edie - who had once dreamed of pursuing a life beyond the confines of her small Vermont town - never left, her dreams disappearing right along with Charlie. In her fifties now, she teaches at her old high school and has returned to her childhood home to care for her ailing mother. When the long-dormant tip line set up for Charlie rings for the first time in years, Edie assumes it's a wrong number - but on the other end is Jericho Jenkins, the only person of interest ever identified in the investigation. Jericho believes he's found something of Charlie's on his property, and with this news, all the pain and uncertainty of that summer rushes back to Edie, including vivid memories of her best friend, Trill: their shared secrets and the devastating lie Edie told that could have changed everything. Now Jericho is under suspicion again, Trill is coming home, and her mother's hope is renewed. Edie's in the same place with the same people as when Charlie first vanished, but somehow everything is different now, and maybe this time they can discover the truth. Everything Has Happened is not only a compelling mystery of a missing child but a story of forbidden young love, a deeply moving novel for readers of Rebecca Makkai and Angie Kim.
