The book took three years to finish “because life kept getting in the way and people kept dying,” she says. She describes how she would walk behind her father, and that she became ‘good at reading the back of his neck.

It takes the form of an extended letter written to the chair of the board of Yad Vashem, Israel’s national Holocaust museum, by a nameless historian who’s found himself trapped in a career as a tour guide of Holocaust sites in Poland – immersive, horror-filled work that’s quite naturally driven him to a nervous breakdown. To summarise, probably more a slice of “life” -well actually, more death, loss and grief, than a slice of cake. Wix’s relationship with her dad pivoted after they were in a serious car accident together that almost killed them. The fact this grief is followed by the loss of her father, and the crushing and unanticipated discovery of her mother’s inoperable brain tumour, is incomprehensibly tragic.

Without the magazines there, to remind me that I should constantly be trying to improve myself and my body, then I would descend into chaos, happiness even.Where the book excels is in its readiness to court controversy without surrendering nuance, and in place of moralising it offers questioning that’s as necessary as it is unsettling. Got this as an audio book and stuck a chapter on to see what to expect, then ended up listening to it for the whole evening and then every minute I could sneak away from what I was supposed to be doing, until it, regrettably, ended. Wix was too shy to perform at school though in an early chapter, she describes an incident where, aged 13, she stole the punchline of a joke being told by a boorish man at a dinner party with her parents.
