Like a sister

"It is 1956 and Sister is only thirteen years old, but she is a mother to her two younger twin brothers and her toddler sister. Her mother, Marnie, has had a string of boyfriends, and her latest is more interested in building up business at his new cafe than he is in raising three children that are not his own. Marnie is involved in the cafe as well - but Sister is not exactly sure how. All she knows is that Marnie isn't around very much."--BOOK JACKET. "Deciding that she will not follow in Marnie's footsteps, Sister begins to take charge of her life, as best she can, by minding her manners, and by befriending her kindly next-door neighbor, Willa, who seems to Sister to be a fine example of how a mother should be. But then Ray Williams, a respected and powerful man in town, begins to notice the blossoming Sister, and when he realizes that she has no adult supervision, he sets his sights on her. Willa steps in to intervene, and Sister thinks she may have found salvation, but in Like a Sister, all is never what it seems."--BOOK JACKET.
