Three River Ranch by Roxanne Snopek

To save his ranch, he needs a wife. But can she save his heart?

Needing a fresh start from her two-timing fiancé, Aurora McAllister answers a realtor's ad for a guesthouse on the beautiful, serene Three River Ranch. She shows up at Three River tired, heartbroken, and with no one but her trusty Labradoodle as a companion.

Cowboy Carson Granger has enough trouble in his life without adding a woman and her dog to the mix. There's the untamed mustang he's prepping to release into the wild, not to mention his father's crazy will, which stipulates that if Carson wants to fully inherit Three River, he'll need to find a bride. Carson wants nothing to do with love and especially not a marriage of convenience. But he soon realizes Rory, and everything she represents, might just be exactly what he needs. Sometimes love arrives on your doorstep when you least expect it...
