Beginning at the End by Viola Grace

Eudora begins with a divorce, finds a lawyer, and discovers that she was never married at all. The lawyer finds that his client glows like the sun to his senses, and it is her focus and professionalism that will see him through. Maybe.

Eudora was in a marriage of convenience, which became inconvenient when her husband brought a woman home, breaking the terms of their prenup. She follows the letter of their agreement and leaves everything behind, but now, his lawyer is stalking her, and she needs legal help.
A coworker calls a lawyer who is willing to work for an exchange of services. He will unravel her divorce and the original marriage, and she will join him at society functions as his plus one to keep women at bay. He agrees to provide the dresses and accessories, and she agrees to the deal.
Unravelling her legal mess is fairly easy once he realizes that half the documentation wasn’t enforceable to begin with. A simple arrangement just got complicated in the weirdest way.
