She’s woken up in a life she doesn’t recognise – with a daughter she doesn’t remember. When Charlotte McKay wakes up in a hospital bed with no memory of how she got there, all she wants is to go back to the perfect London flat she shares with her husband, and the impressive career she’s worked so hard to build. But something’s not right. Her husband David is at her bedside – but so is a three-year-old girl, and she’s calling Charlotte ‘Mummy’… Charlotte’s first instinct is panic. When – why – did she have a child? What about her promotion, her independence, her romantic weekends with David? She loved being that woman: how can she have turned into the stay-at-home mother she swore she’d never be? Back at home, she dives into her unfamiliar world, hoping to piece together the mystery of her transformation. But faced with so much that feels foreign and unnatural, will she ever be happy in a life she can’t remember having – or wanting to have?
