Where the Missing Go

My name is Kate.I volunteer at a missing persons helpline - young people who have run away from home call me and I pass on messages to their loved ones, no questions asked. I don't get many phone calls, and those I do are usually short and vague, or pranks. But today a girl named Sophie called.

I'm supposed to contact her parents to let them know their child is safe. The problem is, Sophie isn't safe. And Sophie is my daughter...
