A Pitiful Remnant — Judith B. Glad

A marriage of convenience. How dreadfully inconvenient...
Lisanor needs a husband willing to marry her immediately, but he must agree to an outrageous condition. Guillemot is all but bankrupt and Clarence, the new marquess, has no choice but to marry for money. She is trained to manage a great estate, he to command a regiment, and neither is willing to give an inch. One of them must yield if they are to work together, to live together, perhaps even to love together.
