Discouraging the Duke by Alexa Aston

Accused of something they never did. Five boys banished from their homes in disgrace, to the place where they find the brothers of their heart—and build new family ties that will last a lifetime.
A lonely army captain who suddenly finds himself a duke. A gentleman’s daughter running an estate because her father no longer can. Two lonely souls whose sparks are undeniable . . .
Miles Notley returns home as the new Duke of Winslow after being sent away for accidentally killing his younger brother when he was ten years old, an act his older brother committed—and denied. With his brother’s death, Miles finds himself in unfamiliar waters. He has no idea how to run an estate, much less be a duke. Until he meets an intriguing young woman.
Emery Jenson came to Wildwood ten years ago with her parents, hired to be the estate’s steward and housekeeper. She has taken on more responsibility as her father’s mind grows weak and now runs the ducal country seat. When the new duke shows up, she schemes to hide her father’s deficiencies, believing the Duke of Winslow won’t remain long since the Season is in full swing and he will need to claim a bride and provide an heir.
But Miles isn’t going anywhere. He becomes captivated not only by Emery’s charm and confidence but admires her skills in making Wildwood a profitable estate. Miles decides no one but Emery can be his duchess—and he is up for the challenge, ready to convince the blunt beauty in the battle of wills that they can both come up winners—if she will only say yes.

Will Emery, who thinks she has found her place in the world and urges Miles to now find his, discover that the best place she can be is at the Duke of Winslow’s side?
