Saz Martin is settled into new motherhood with her partner Molly and their nine-month-old daughter Matilda. Things have not been easy since the birth - late nights, early mornings, and a sudden death have all taken their toll - but with Molly's return to full time work and Saz happily taking on the role of Matilda's prime carer, both women feel they are finally adjusting to parenthood and the demands of their new life. And then the phone rings. The door knocks. A well-known stranger arrives. Instead of moving forward into her role as a full time mother, Saz is forced to face her past, confronting people and events she had long ago hoped to forget. In a story of how the sins of our past always come back to haunt us, Stella Duffy reveals secrets no-one knew about Saz Martin, explores why Saz is who she is, and asks is it still possible to believe in our heroes - and our lovers - when their flaws are well and truly exposed?
