Book excerpt: 'There's only been one time that Rose couldn't stop me from doing the wrong thing and that was a mistake that will haunt me for the rest of my life.' Fern Castle works in her local library. She has dinner with her twin sister Rose three nights a week. And she avoids crowds, bright lights and loud noises as much as possible. Fern has a carefully structured life and disrupting her routine can be . . . dangerous. When Rose discovers that she cannot fall pregnant, Fern sees her chance to pay her sister back for everything Rose has done for her. Fern can have a baby for Rose. She just needs to find a father. Simple. Fern's mission will shake the foundations of the life she has carefully built for herself and stir up dark secrets that she long thought were buried. **************************************************** Praise for Sally Hepworth: 'Women's fiction at its finest' LIANE MORIARTY 'Clever, chilling and beautifully crafted' ADELE PARKS 'The characters are so beautifully drawn and it was an emotional read, but I couldn't put it down' HEIDI PARKS 'Sally demonstrates that you don't need outlandish situations and monstrous characters to write a thoroughly engrossing, suspenseful thriller, and her writing feels so effortless' EMMA CURTIS 'It's not often that such a gripping page-turner can be so moving' SARAH NAUGHTON 'Cleverly plotted and completely compelling' NICOLA MORIARTY
