Sophie Winter lives in a self-imposed cocoon - she's a single, thirty-one year old translator who works from home in her one bedroom flat. This isn't really the life she dreamed of, but then Sophie stopped believing in happy endings a very long time ago, when she was fifteen years old and tragedy struck her family. Her grief has left her scared of commitment and completely risk averse, so she plays it safe and keeps everyone at arm's length. Sophie understands she has a problem, but recognising it and knowing how to fix it are two entirely different things. One night a serious fire breaks out in the flat below hers. Sophie is trapped in the burning building until a random passer-by, Ben, luckily happens to spot and rescue her. Suddenly her cocoon is shattered - what will be the consequences of this second life-changing event?
