Missing in Salem

Esmeray Smith has been forced to do many things in her life: move to a new country, a new school, have to put up with her obnoxiously popular sister, and study her ass off. But she never expected she'd be forced into solving a mass kidnapping after her younger sister, Mallory, goes missing one day after a club at school.
With her parents utterly distraught and her community terrified after reports of cultist sacrifices start to appear on the news, Esmeray and her best friend, Lawrence Montgomery, must work together to track down her sister's kidnapper and stop the culprit from taking any more children before it's too late.
Will they succeed? Or will they run out of time?
