FROM THE MILLION-COPY BESTSELLING AUTHOR'An inspired set-up. A clever dynamic that paves the way for a cat-and-mouse thriller. Propulsive.' SUNDAY TIMES'A maze-like game of revenge. Unsettling. Blends a critique of wellness culture with a slow-burn feminist thriller.' OBSERVER'If you spend all of January trying to avoid diet culture, then you need to read this book.' COSMOPOLITANAll Liam ever wanted was to help me reach my full potential. And he always knew what was best. Until the day he pushed me far beyond my limits, and I walked out of our flat and away from our relationship to good. Now, two years on, I am stronger, fitter, healthier than ever before. And then I see him – Liam – those green eyes, those stirring muscles. Something inside me flips. I want revenge, and I’m willing to do almost anything to get it. I hold the power now. It’s Liam’s turn to sweat. 'Will have you glued to the story through every twist and turn. I absolutely adored it!' KATE HAMER, bestselling author of The Girl in the Read Coat'Sweat is like nothing I've ever read before. So addictive it made me miss a tube stop, so unsettling it made me think twice about going to the gym!' SARA COLLINS, author of The Confessions of Frannie Langton'Taut, compulsive, and unsettling ... It had me holding my breath until the final, brilliant end' JENNIE GODFREY, No.1 Sunday Times bestselling author of The List of Suspicious Things
