Angie, 6, and sister Polly, 4, are utterly distraught when they arrive to stay with foster carer Cathy Glass. Their older half-sister Ashleigh has accused their father of something horrible, and the two young sisters have been removed from home to keep them safe.
Cathy has been a foster carer for over 30 years, during which time she has looked after more than 150 children, of all ages and backgrounds. She has three teenage children of her own; one of whom was adopted after a long-term foster placement. The name Cathy Glass is a pseudonym.
