Books like Celeste Ascending

In this splendid novel, Celeste finds herself engaged to Alex, a wealthy man whose standards are as exacting as her own -- or so she thought. As she begins to question their relationship and herself, Celeste is haunted by painful memories: of her past in well-heeled, blue-blooded Connecticut; of the friends and family who seem to have disappeared from her life; and of Nathan, for whom Celeste still carries a lingering passion. At last coming to terms with the lies and illusions that have propelled her forward for years, Celeste must take responsibility for the choices she has made. She decides to be true to herself -- and so challenges her fiancé, her family, and the very society in which she's steeped.
