In Need of a Duchess by Violet Hamers

After being stuck to Canada for years because of the war, Alice finally steps foot on British soil again. However, home is not how she remembers it. And marrying to escape her cousin’s advances seems like the only way to save herself.
Donovan’s nephews are the bane of his existence. And despite his glorious career in the military, he cannot distill any kind of obedience to the little menaces. His last resort? A Duchess with nerves of steel.
When the Duke saves a damsel in distress only to have her hold a dagger to his throat, he knows he has found the woman he was looking for. Only… Alice proves to be too feisty for him to handle. And even more tempting to resist.
