For fans of Sarah Pinborough and Liane Moriarty comes a taut domestic suspense about the lies we tell to hold our lives together.

Sisters, like secrets, are best kept close.

Penny and Hattie, orphaned sisters in a small town, are best friends, bound together to the point of knots. But Penny, at the mercy of her brutal husband, is desperate for a fresh start. Willing to do anything for her older sister, Hattie agrees to help. A match is struck and a fire burns Penny’s marriage to the ground. With her husband gone, Penny is free, and the sisters, it seems, get away with murder. But freedom comes at a cost.

More than a year after the fire, a charming young man comes to town. Hattie and Penny quickly bring him into the fold and into their hearts but their love for him threatens the delicate balance. Soon long-held resentments, sibling rivalry, and debts unpaid boil over, and the bonds of sisterhood begin to snap. As one little lie grows into the next, the sisters’ secrets will unravel, eroding their lives until only a single, horrible truth remains: You owe me.

A compelling novel of suspense from a talented new voice, Sister of Mine asks us to consider the bonds of family, what it takes to commit the unthinkable, and how far you’ll go to protect the ones you love.
