Welcome to Grosvenor Ranch, where this rough and rugged cowboy is about to discover everything he’s ever wanted . . . in one cute, curvy, and totally off-limits package.

Beau Black is ready to take the reins of the Grosvenor Black Cattle Ranch. A man of few words and many responsibilities, it’s his job as the eldest son to hold on to the family legacy for his two brothers while raising his four-year-old twins. Alone. Carrying the guilt and grief of his failed relationship with the woman who left him before her death, Beau refuses to let anything—or anyone—distract him from what’s important in life: his family and their land. Even if that means closing his heart to love.

Until his ex’s long-lost younger sister appears in his life . . . and makes his resolve crumble.

Hallie Lockhart is a breath of fresh air in Beau’s dusty world, a reminder that life isn’t just about duty and tradition. When she offers to help his family for the summer, the chemistry between them becomes undeniable. But Hallie is his girls’ aunt, so she’s absolutely off-limits.

As friendship becomes more, can the two fight the passion building between them? Or are they destined to learn that love doesn’t always follow the rules?
