At Top Speed (Quartz Creek Ranch)

For Ella, winning has always been the goal, and at Quartz Creek Ranch, she's pretty sure she'll ace horseback riding too. There's just one hitch in her plan: Figure Eight, the beautiful quarter horse she's paired with, won't listen to a word she says.

Struggling with Figure Eight could be the motivation Ella needs to control her ego and temper―especially when she's turned on to barrel racing. Figure Eight would be incredible at it, she knows. But quiet, sensitive Jordan is the only one on the ranch with time to teach Ella those high-speed turns. Suddenly Ella faces a new challenge on her road to success: figuring out how to be a good friend.
