The Bride objected. The Groom insisted. The Wedding was for the children's sake. Bringing home the wrong baby-a one-in-a-billion chance. Yet Cassie Arnold's sister, Susan, was convinced it had happened to her. After Susan's death, Cassie felt obliged to investigate the possibility. And she discovered that Susan was right! Divorced Phoenix banker Trace Ramsey had Susan's real son--Cassie's nephew. Cassie had his. Trace was powerful, influential and a devoted father, not a man to settle for half measures. He wanted both children and so, of course, did Cassie. He insisted there was only one solution: she'd have to marry him.
