Lenny Marks is good at not remembering. She has spent the last twenty years not thinking about the day her mother left her when she was still a child. Her stepfather's parting words, however, remain annoyingly unforgettable- 'You did this.' Now thirty-seven, Lenny prefers contentment and order over the unreliability of happiness and the messiness of relationships. She fills her days teaching at the local primary school, and her nights playing Scrabble with her pretend housemate, watching reruns of Friends and rearranging her thirty-six copies of The Hobbit. Recently though, if only to appease her beloved foster-mum, Lenny has set herself the goal of 'getting a life'. Then, out of the blue, a letter arrives from the Adult Parole Board. And when her desperate attempts to ignore it fail, Lenny starts to unravel. Worse, she starts to remember . . .
