Three long-time best friends. Countless problems that threaten their happiness. And one stubborn old mare that brings them back together.

After a terrifying incident on horseback, Vanessa quits riding entirely. But now that she's in business with her childhood besties who both still ride, she's being pressured to pick it back up. When the women stumble upon an old mare who also happens to be injured, Vanessa sees something in the horse. She decides to try rehabbing the mare in spite of the lousy odds of recovery.

Now that Samantha's come clean with her boyfriend about a secret, she's newly single. Again. But that's fine. She's done waiting to build the life she always wanted, and she's moving full steam ahead.

While her friends both deal with their own drama, Natalie's holding down the Fort?the Fortwilliam Estate, that is. She's running their castle-turned-hotel, and they're halfway through the slow season. That means summer's coming, and they need to be ready. But things keep getting in the way of her preparations, and Natalie's starting to wonder whether they're really the partnership she'd hoped.

When a disaster strikes the heart of their little family, Natalie, Samantha, and Vanessa must come together to keep the things that matter safe. Can these three friends rearrange what doesn't work and repair the things that do? Or will their stubborn natures keep them from finding the greener pastures they all need?
