"In this book, Barbara Grenfell Fairhead has successfully captured quicksilver - the inchoate, the unintelligible, the mystery of the landscape of the primordial mind. It is an extraordinary achievement. The only other book that came to mind while reading it is the award-winning book, Riddley Walker by Russell Hoban. Her book takes us even deeper into the early landscape of language and the earliest human earth."
