Tina Harker loves malls, manicures, fun clothes, and horses. She has everything she wants until her dad moves the entire family to Arizona. She's trying to adapt to the tiny town, serious lack of a mall, and the strangeness of the desert, not to mention the rattlesnakes. There's no one in Golton her age and no reason to wear any of her fun makeup. The only thing keeping her going is the horse she rides and the cool things she's learning on the Taggarts’ cattle ranch. Anxious for more adventure, Tina agrees to inspect the fence line for the Taggarts like a real cowgirl. She gets more than she wished for. This time she has to rescue the cute cowboy. Along the way, she finds out people will kill over water. Especially in the desert. Tina is determined to help her cowboy, but she has no idea how, or if, a Jersey girl can stand up to real gunslingers.
