Maggie Carter knows Victoria Park like the back of her hand. She can tell you what time of year the most fragrant flowers bloom; she knows which paths lead you to the bench by the lake. But Maggie is blind. The park is her safe place - because outside it, expecting her first baby, Maggie has started to wonder whether she's going to be able to cope. Elsa, too, is expecting her first child, and alone and without anyone to support her, she is terrified that her child will be taken away. But all is not as it seems: the secrets of 60 years ago are haunting Elsa and they won't let her rest.
