But Molly keeps talking about a little sister that she 'used to have'.
In this story, Casey, determined to find out the truth and advocate for the children in her care, investigates Molly's story and attempts to work out the truth.
But will Casey be able to work out what is true before it's too late?
Casey Watson, who writes under a pseudonym, is a specialist foster carer. She and her husband, Mike, look after children who are particularly troubled or damaged by their past.
Before becoming a foster carer Casey was a behaviour manager for her local comprehensive school. It was through working with these ‘difficult’ children – removed from mainstream classes for various reasons – that the idea for her future career was born.
Casey is married with two children and three grandchildren.
