Rosie Lewis is a full-time foster carer. She has been working in this field for over a decade. Before that, she worked in the special units team in the police force.
Based in northern England, Rosie writes under a pseudonym to protect the identities of the children she looks after.
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.
