Enemy of the Cowboy by Sierra Gamble

Will she realize too late that they don’t have to be enemies?

Evelyn Johnstone is the eldest of seven sisters. When their parents die in a tragic car accident, she must step up to prevent her family from falling apart.
Stephen Sampson is a former cowboy turned businessman who is ready to move onto greener pastures, literally. Blue Moon Ranch is up for sale, and he plans to buy it.
Only Evelyn has something to say about that. Her parents left her and her sisters a million dollars each, and the Johnstone sisters wish to buy the ranch they and their parents worked at.
From the start, Stephen and Evelyn are enemies, but maybe a bit of Christmas magic as well as wedding nuptials between Evelyn’s cousin and Olivia the matchmaker will help a grieving heart find love.
