Nicholas Hamilton was not in the market for a wife and family until his parents made him an offer he couldn't refuse. If he married Moira, the girl who his philandering twin brother had gotten pregnant, they would give him the money for his software startup company.
Marrying a woman and claiming her child as his seems a small price to pay for the business of his dreams until he finds himself attracted to his new wife.

Moira can't believe that one night of bad choices means that now she has to marry a perfect stranger. If she can get Nicholas to invest half as much time in their marriage as he does in his new company, they might just have a chance at happily ever after.
