Marshal Shay McQuillan has a lot on his hands -- stagecoach robbers to hunt down, a murdered fiancée to avenge. He certainly doesn't need an identical twin brother he never knew existed turning up out of the blue and telling him what to do. Even less does he want pretty Aislinn Lethaby trying to rescue him from danger. Because, to tell the truth, Aislinn is a sweet distraction from duty whom Shay just can't resist.
Aislinn Lethaby has a fine job at the town hotel. Soon, she'll have saved enough to buy the broken-down homestead she has her eye on and bring her young brothers west. She has no business jeopardizing everything when she sees Shay in danger. But something about the man makes Aislinn lose all the good sense she thought she had -- and follow the longings of her heart.
Now that he's finally found his twin brother, all Tristan Saint-Laurent wants is to be a peaceful rancher. What he gets is Miss Emily Starbuck, a determined package of trouble from back East. Tristan knows he should tell Emily and her aggravating sheep to move along, but he doesn't have the heart. Suddenly this man of danger is dreaming of weddings and babies. But the life he's left behind may yet come between him and the woman he's growing to love.
Emily Starbuck is making a fresh start by raising the sheep she's bought with a meager inheritance. She's willing to fight every cattleman in the West, but she can't resist Tristan. His handsome face and lean, strong body make her knees buckle, and her thoughts move to sharing a blissful ranch life with the man. But what Emily doesn't know about Tristan could jeopardize their dream of happiness.
