A taut YA crime thriller from the author of The Body of Christopher Creed. “There’s no doubt Plum-Ucci can tell a heck of a story” (Booklist). A tiny pistol, passed from friend to friend at a party on an abandoned pier, suddenly fires—and Casey Carmody falls into the water below. Kurt, Casey’s older brother, endures a seemingly endless night at the police station while the coast guard searches for his sister and his friends are questioned, one by one. Was the gunfire accidental or deliberate? Or was the whole drama one of Casey’s practical jokes? And where is Casey—or her body—now? “The Night My Sister Went Missing has all the suspense and drama of a locked-room mystery . . . Carol Plum-Ucci, author of the award-winning The Body of Christopher Creed, has crafted an intricate mystery filled with shocking surprises and characters whom readers will remember for a long time.” —Teenreads “Plum-Ucci’s mastery at intensifying their observations into something dire and ominous speeds the plot along and should keep readers wondering just how this convoluted mystery will wrap up.” —Kirkus Reviews “All the members of this loosely connected community harbor secrets they do not want to be revealed. But in the end, someone’s secret comes to light with devastating consequences.” —Publishers Weekly “The mystery is engrossing and the dramatic ending satisfying.” —School Library Journal
