On Gallows Hill by Lynda Styles

Salem, Massachusetts still has a great deal of healing to do... Seventeen year old Katelyn King never speaks at school, and everyone has finally stopped talking to her. They call her The Mute, but what they don't realize is Katelyn can see ghosts and is a psychic-medium. Katelyn is visited by the ghosts of Salem's dark past, and she realizes she has no choice but to get over her fears and learn how to help them find peace. When Katelyn is paired on a History Project with the popular Cassie Wallace and Laenie Pratt, she knows that her secret can't be kept forever. After they begin the project together, Cassie Wallace, a pretty cheerleader who loves to party, is kidnapped by a delusional online predator and held captive in one of Salem's scariest tourist attractions. Katelyn tries to keep her secret under wraps and help find Cassie before it's too late. This tale has gripping twists and turns, sure to entertain the Young Adult reader and many more.
