A Bride for David (The Proxy Brides #37)

Mathematics teacher Daisy Murphy agrees to participate in a new matchmaking service organized by her pastor and the matron of the orphanage where she has spent the last fifteen years. Romantic, yet practical, she's systematically eliminated all candidates but one and anticipates getting to know him better through months of correspondence.
Time is not on the side of David Taylor. He has a nephew and niece to think about, and his attorney has warned him he will lose custody of both to their rich grandfather if he doesn't have a wife. A teacher longing for security, a businessman about to lose the only family he has; and a proxy marriage that can give them both exactly what they need.
