Brown, SandraFrom Publishers Weekly Soap opera star Cat Delaney gets a new heart--literally and figuratively speaking--in bestseller Brown's (French Silk ; Where There's Smoke) latest contemporary romance. The heart transplant that beautiful, arrogant Cat endures in the first chapter transforms her soul along with her cardiovascular system. If Brown had first established Cat's personality with some depth and credibility, that might have been the basis of an emotionally involving story. But since Cat is little more than a vessel for the concept, before we can blink, she is a good-hearted citizen who abandons stardom and Hollywood for San Antonio, Tex., where she hosts a local TV program featuring children up for adoption. Cat hardly has a chance to enjoy her change of heart and her new heartthrob, bad-boy crime novelist Alex Pierce, because a stalker is after her. Three potential heart donors are knocked down like dominoes: obviously the stalker is a bereaved nut determined to kill all the transplant recipients who might have received his lover's heart.
