When Christina Patterson's brother Tom died suddenly, she faced the harrowing task of clearing out his house. Tom had always been the one who held on to the family treasures and memories, but now Christina had to sift through boxes of letters, photos and belongings, not just of Tom's, but of their parents and their older sister, Caroline.

The contents of those boxes tell the story of a young couple who decide to swap a glamorous diplomatic life in Rome for a housing estate in Surrey. But their new suburban, happy life, is increasingly disrupted by Caroline's erratic behaviour. As she is diagnosed with schizophrenia, Tom seeks solace in sport and Christina in a youth club where she hopes to meet boys, but finds God instead. It doesn't help her in her quest for romance.
