Louise's biological father, formally Brian, underwent a sex-change operation to become Sarah - now he's mum. Sarah's partner, truck-driver Kate, was also born male (Lee), but later transitioned and is now Louise's other 'mum.'
Louise's biological mother, Hayley, has remarried and is no longer part of her life.
Confused? Louise isn't.
Since the news of this unusual family broke, the tabloids dubbed Louise, Sarah and Kate 'Britain's Weirdest Family.' Now Louise's classmates tease her, but instead of hiding away, she's determined to set the record straight and prove that even though her family may not be ordinary, it works.
This extraordinary story is seen through the eyes of Louise as she tries to come to terms with the unwelcome, and hostile, attention her family has attracted. Louise retraces her family's recent history explaining how she coped with Sarah and Kate's sex-change operations: Her dad was now her mum and his gay male partner was now his lesbian partner. Louise also goes on a journey to work out exactly what makes a 'normal' family and whether or not that really matters. In an attempt to reach out to others like her, Louise befriends a 12-year-old boy whose step-mum is transsexual and meets a woman whose children disowned her when she changed sex.
Interspersed with intimate actuality showing what it's really like to be transsexual, Louise's quest to defend her unusual family is both intriguing and touching.
