for The Night My Sister Went Missing by Carol Plum-Ucci
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.Who was foolish enough to pull the trigger? 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?Dark secrets are revealed and petty jealousies rear their ugly heads as each eyewitness comes to the questioning room with his or her own version of "the truth."
