Work, power, and success are the idols attorney Madison Barnes worships, and she's never allowed anything, or anyone, to interfere with attaining them--except for her younger sister Dee. To help her sister out, Madison reluctantly agrees to spend a weekend with Dee's closest friend, a smart-ass troublemaker Karlie Henderson. To Madison's consternation, she discovers that the opinionated young college activist she remembers has turned into a wildly popular romance author and an attractive, exciting woman she can't quite keep out of her thoughts. Karlie's life is in complete upheaval. Depressed and troubled, she's not looking forward to spending a weekend trying to be polite to her best friend's arrogant older sister. Memories of their past encounters leave both women unprepared for the different kinds of sparks that arise when they spend a day together on Madison's yacht. Suspicious of Madison's motivations, Karlie has no choice but to return home and try to move on with her life--but the damage has already been done, and the consequences may be deadly.
