Walking Summer

Will Piper be able to ride again?Nearly two years ago the car she'd been riding in with her best friend crashed, leaving Piper unable to walk, let alone ride her horse, Amigo. Shortly after the accident Chloe, her best friend and the car's driver, moved away. Piper hasn't seen or heard from her since. She's been spending her time regaining strength, and when she finds a flyer for a local therapeutic riding program, she feels like this is her chance to get back in the saddle.
But as she finishes her sophomore year, she discovers Chloe is returning and needs a place to board her horse. Piper makes the offer for Chloe's horse to stay with her, hoping  she can regain the friendship they once had. But Chloe's changed. She'd always been the adventurous one, but Piper soon realizes there's something more going on with her friend. And she wonders if she ever knew Chloe at all.
All Piper wants is to ride Amigo again, and competing in the show at the end of the summer makes the perfect goal. But will she move too fast and end up jeopardizing her chances of getting back in the saddle at all? And will her friendship with Chloe survive the summer?
