Combining the sexual frankness of Fifty Shades of Grey and of Belle de Jour's writing, with the fascinating insights of What the Nanny Saw, Scarlett O'Kelly's memoir of her year as a high-end escort, Paying For It, is an explicit, astonishing and compulsive story of living a double life .

Facing financial meltdown, mother of three Scarlett O'Kelly did what the average woman would find unthinkable: she set herself up a sex worker. There was the sex, which, surprisingly for Scarlett, could have unexpected pleasures. Then the clients - ordinary men who worried that they had to hide their sexual needs, desires and fantasies from their wives or girlfriends. Not to mention her realisation that women just like her could build stronger relationships if they could let go their hang-ups in and out of bed. And there's the high price Scarlett paid for her double life - one she is still coming to terms with.

Paying For It is a raw, intimate and powerful story of one brave woman's sacrifice in a time of hardship. It is a searingly honest and truly eye-opening account of modern life and what really goes on in couples' bedrooms.

It is also an intriguing and risqué account of one woman's sexual odyssey - from her decision to make money from sex to her realisation that she had become sexually liberated in the process.

Scarlett O'Kelly is a middle class everywoman - and her clients were ordinary middle class men - so this is an intriguing picture of a side of life that is usually hidden.
