My name is Kate.I volunteer at a local charity – 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 this morning 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.
