Words are important to Gretel, always have been. As a child, she lived on a canal boat with her mother, and together they invented a language that was just their own. She hasn’t seen her mother since the age of sixteen, though – almost a lifetime ago – and those memories have faded. Now Gretel works as a lexicographer, updating dictionary entries, which suits her solitary nature.A phone call from the hospital interrupts Gretel’s isolation and throws up questions from long ago. She begins to remember the private vocabulary of her childhood. She remembers other things, too: the wild years spent on the river; the strange, lonely boy who came to stay on the boat one winter; and the creature in the water – a canal thief? – swimming upstream, getting ever closer. In the end there will be nothing for Gretel to do but go back.Daisy Johnson’s debut novel turns classical myth on its head and takes readers to a modern-day England unfamiliar to most. As daring as it is moving, is a story of family and identity, of fate, language, love and belonging that leaves you unsettled and unstrung.
