Promise Me — Margaret Allison

Alexandra Webster is an accomplished reporter for The New York Times whose career--and life--has hit a slump. She jumps on a potentially explosive story when the socialite wife of business tycoon and former Olympic boxer Steve Chapman dies under mysterious circumstances. Certain that Steve Chapman is guilty of murder, Alex gains access to his estate, isolated on a rugged tropical island in southern Florida, by going undercover as a horse trainer. But she is completely unprepared for the attraction she feels for the man she thinks is a killer.

As she works her way into Steve Chapman's world, Alex's suspicions slowly give way to a heartfelt belief in his innocence. Far different from what she expected, Steve is a man who fights to protect his young son from tormenting rumors, and who struggles to put his painful marriage behind him. And she can't ignore that he is undeniably drawn to her.... Caught in the grip of an unexpected passion, Alex and Steve step cautiously among the lies and secrets that brought them together. But as their love deepens, Alex's deception becomes even riskier and she fears that her own ambitious scheme may shatter the trust and caring that have brought them so far.
