However, it was inspired by almost fifty cases of so-called Fasting Girls—hailed for surviving without food for long periods—in the British Isles, Western Europe, and North America between the sixteenth and the twentieth centuries. These girls and women varied widely in age and background. Some of them (whether Protestant or Catholic) claimed a religious motive, but many didn’t. There were male cases, too, though far fewer. Some of the fasters were put under surveillance for weeks on end; some started eating again, voluntarily or after being coerced, imprisoned, hospitalized, or force-fed; some died; others lived for decades, still claiming not to need food. Thanks for crucial suggestions go to my agents Kathleen Anderson and Caroline Davidson and my editors Iris Tupholme at HarperCollins Canada, Judy Clain at Little, Brown, and Paul Baggaley at Picador. Tana Wollen and Cormac Kinsella kindly helped me keep my Hiberno- and British Englishes straight, and Tracy Roe’s copyediting was as ever, and in both senses, priceless.
