"Jeanette Winterson once asked her adoptive mother — stringently immortalised in her first novel ' — why they couldn't have books in the house. "The trouble with a book is that you never know what's in it until it's too late," answered the peerless Mrs Winterson. As advertisements for reading go, it's pretty seductive. But it also happens to be wonderfully true of this vivid, unpredictable and sometimes mind-rattling memoir. You start it expecting one thing — a wry retake of her gothic upbringing – and come out having been subjected to one of the more harrowing and candid investigations of mid-life breakdown I've ever read. This book is definitely of the sort that Mrs Winterson feared most: truths that most of us find hard to face, explored in a way that disturb, challenge, upset and inspire. And so yes, by the time I realised what it was really about and what it was going to do to me, it was definitely far "too late"."
