As Chloe Cozens mourns the death of her mother, Lesley, teenage 'delinquent' Nicky Nelson experiences quite a different emotion towards her, his social worker, the one person he thought he could rely on when everyone else had let him down. When Nicky begins hanging around Chloe's house with a mixture of curiosity and anger that she has had a happy life compared with his, he is prepared to hate her, but instead the two of them form a strange kind of bond. Chloe finds herself wanting to help Nicky find his real mother, the one who abandoned him at birth. Ironically, the clues she pieces together about what happened lead her back to her mother's home town, and to her childhood friend, Sonia, who is keeping a painful secret of her own. Chloe finds comfort in helping Nicky, a boy who is almost like a brother in that her own mother looked out for him for so long, and Nicky discovers that sometimes you have to trust in people in order to move on and build a life...
