Don’t Let Her Stay by Nicola Sanders is a psychological thriller that tells the story of Joanne — a new mother — whose life begins to unravel when her husband’s estranged 20-year-old daughter, Chloe, unexpectedly moves in. What starts as a hoped-for reconciliation quickly turns sinister. Joanne begins to notice unsettling events: strange behaviour, subtle manipulations, and disturbing signs that Chloe might have dark secrets. As Chloe integrates into the household under the guise of helping and bonding with the baby, Joanne’s sense of safety and reality begins to crumble. The novel builds tension through creeping paranoia, gaslighting, and mounting dread — forcing the reader to question every interaction and motive. The world Joanne relies on (her home, her husband, her family) slowly becomes hostile, as she fights to protect her child and uncover painful truths.
