The Hitch Hiker.

19 year old Peyton didn't know what she wanted. With college waisted on a useless course to help her run the family business, she was constantly living in the shadow of her elder sister. No wonder she never got a tan.
But then she picked up Delia; an intriguing, exciting hitch hiker who was more prepared for life than anyone Peyton had ever met before.
As they journey down Route 66, a phenomenal bond forms in a glorious tale of extraordinary friendship, self-discovery, and of course, a heart-warming romance with a cute mechanic.
