Younger Daddy by Ava Sinclair

Spending a week on a working ranch is a dream come true for Paisley O’Brian. Even though it’s a professional retreat, she’s overjoyed to revisit her childhood passion and get back on a horse.
But when strong, gorgeous Emmett Holden rescues her from a disastrous trail ride, she suddenly finds herself consumed by an entirely different kind of passion.
Despite being twelve years her junior, Emmett’s dominant nature taps into a side of herself she thought she’d buried long ago. Every touch, every kiss, every growled promise to put her over his knee just makes her want him more, even if their budding romance is only temporary.
Because in spite of Emmett’s determination to prove otherwise, Paisley knows she’s damaged goods. But Three Forks Ranch has a reputation, and it’s almost enough to make her believe in fairytales again.
Could a hot, younger cowboy really be the Daddy she’s waited her entire life to find?
