#1 in Adventure 6/16/2015 Taylor Evans, a foster child, has been planning her runaway for a while now. Ever since her parents died when she was 6, she's been moved from foster home to foster home, and she's sick of it. So she runs away, train hopping until she gets far enough away. When she gets off, she realized her new surroundings are eerily familiar, and a strange sense of déjà vu follows her everywhere. When she finds the horse, she feels so bad for it- it's owner abuses it. And so her journey begins- a journey full of adventure, danger, and budding love... and horses.

When Sadie was 18, her parents were killed in a car accident, leaving her all alone on her ranch with her quarter horses. Most of them she sold off, but she kept a few favorites to show and breed. University doesn't have a place in her mind;horses are the only thing that matter to her now. Then, on a visit to a family friend's farm, she sees an ordinary bay gelding, who she becomes interested and buys. This horse is special though. It has a secret talent, and its up to Sadie to find it.
