Want Me, Cowboy (A Copper Ridge Desire 5) by Maisey Yates

Her rancher boss is looking for the perfect wife…and she wants the job!

Poppy Sinclair kept her feelings for Isaiah Grayson secret for a decade. When her infuriatingly gorgeous Stetson-wearing boss enlists her help in finding him a convenient wife, she threatens to quit. Until Isaiah counters with an interesting proposal: Why doesn’t she marry him? Can she say yes to sharing his life and his bed, but not his heart?
