Gone Missing by Linda Castillo
Rumspringa is the time when Amish teens are allowed to experience life without rules, but everything changes when a child goes missing.
A missing child is a nightmare to all parents, and never more so than in the Amish community, where family ties are strong. So when a body turns up and another young girl goes missing, fear spreads through the community like a contagion. Kate and state agent, John Tomasetti, delve into the lives of the missing teens and discover links to cold cases that may go back years. But will Kate piece together all the parts of this sinister puzzle before it’s too late? Or will she find herself locked in a fight to the death with a merciless killer.
