Misery loves company. Anyone who doubts this old adage should pop into their local bookshop, because besides celebrity chefs and Fifty-Shades-of-Grey-style erotica, what keep the tills ringing are misery memoirs. The shelves are groaning with them. Their titles can vary from the merely toe-curling (Cry Silent Tears) to the queasily exploitative (Please, Daddy, No), but even if the names of the characters vary, all these books share the same basic plot.
