==Book Description==
For Emily Ann Carr, life has been a series of obligations. Putting aside hopes for love and a family of her own, Emily raised her niece and nephew after the death of her brother. Now, with the children grown and gone, she has time to revisit some of her own dreams.
More than twenty years her senior, Emily Carr's spinster aunt Carolyn Sheffield is "terminally single and proud of it." Sure, she's pleased to know that her favorite niece has found love, but such nonsense has no place in her own life...or does it? When Carolyn finds herself being diligently pursued by a handsome, good-natured widower, will she allow the walls she's built to crumble?
