When Fitzwilliam Darcy inherits an unexpected title, he gains more than London property and social duties. He also inherits guardianship of his late cousin's illegitimate son, a spirited toddler who topples towers and spoons out chaos with equal authority. To keep custody, Darcy must marry at once.

Enter Elizabeth Bennet: clever, scandal-touched, and far too independent for London's taste. A year in Paris studying art has given her talent, confidence, and a reputation society whispers about. When her brother-in-law proposes a marriage of convenience to Darcy, Elizabeth accepts for the boy's sake, and perhaps her own curiosity.

Their union begins as strategy. But in a house filled with spoons, stubborn latches, gossiping maids, and Caroline Bingley's relentless meddling, strategy quickly gives way to hilariously inconvenient affection. From nursery mishaps to drawing-room duels of wit, Darcy and Elizabeth discover that family is not found in ledgers or titles; it is built in laughter, trust, and the courage to be inconveniently oneself.

A Regency romcom brimming with forced proximity, grumpy-and-sunshine banter, and one adorably precocious child, Most Ardently, Most Inconveniently is a heartwarming tale of how love, like family, often arrives in the most unexpected, and inconvenient, ways.
