Riding for Redemption by Bonnie R. Paulson

A rodeo queen who can’t walk, a lovesick cowboy, and their friendship that suddenly becomes more…

Riding horses anchors Sara Beth. It’s something she can always count on–until a near-fatal accident leaves her paralyzed from the waist down. Not only is her back broken, but her spirit is crushed as well.
When Johnny rides into her life and they become fast friends. He’s hired by Sara Beth’s family and it isn’t proper to be seen dating family of the boss. Johnny has to hide his feelings for Sara Beth or lose his chance to get the ranching knowledge his family sent him to gain.

But Johnny soon has Sara Beth convinced that she isn’t defined by her ability to walk and she’s fast losing her heart to the tall, hardworking cowboy.
