Play Nice by Rachel Harrison

Clio Louise Barnes leads a picture-perfect life as a stylist and influencer, but beneath the glossy veneer she harbors a not-so glamorous secret: she grew up in a haunted house. Well, not haunted. Possessed. After Clio’s parent’s messy divorce, her mother, Alex, moved Clio and her sisters into a house occupied by a demon. Or so Alex claimed. That’s not what Clio’s sisters remember or what the courts determined when they stripped Alex of custody after she went off the deep end. But Alex was insistent; she even wrote a book about her experience in the house.

After Alex’s sudden death, the supposedly possessed house passes to Clio and her sisters. Where her sisters see childhood trauma, Clio sees an opportunity for house flipping content. Only, as the home makeover process begins, Clio discovers there might be some truth to her mother’s claims. As memories resurface and Clio finally reads her mother’s book, the presence in the house becomes more real, and more sinister, revealing ugly truths that threaten to shake Clio’s beautiful life to its very foundation.
