For the Babies' Sakes (Expecting) (Harlequin Presents, No. 2280)

Helen was very much in love with her tall, handsome husband, Dan–but she'd caught him in flagrante with his secretary, and now their marriage was over. Actually, Dan had never betrayed her–Helen had got the wrong idea.
But he didn't see how their marriage could work if Helen didn't trust him. Then they discovered Helen was expecting twins! Now Dan has no choice but to be a full-time father…and husband?
