"The story started slowly but soon picked up pace leaving me unable to put the book down."
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.
