Sister of mine
(Book)

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. -- from Amazon.
