Wishing Jar by Penelope J. Stokes

Abby Quinn McDougall is a Southern lady whose once picturesque small-town life seems to be shrinking. Widowed at fifty and burdened by the care of an ailing mother and a cantankerous teenaged daughter, Abby wishes her life were simpler and her responsibilities fewer. Abby's daughter, Neal Grace, devastated by the loss of her doting father and the illness of her beloved grandmother, wishes for change, for the chance to break free from other people's expectations. And Abby's mother Edith wishes only to be liberated from life itself.

But wishes often backfire. As their wishes begin to come true, the Quinn women start to wonder: Could it be that their old life wasn't so bad after all? Is it possible that the answer to their deepest longings has been right in front of them, all along?
