White Ghost. Wind Riders, #4

Pulled out of school early, pampered and entitled daddy's girl Gwen and her parents set off on a multi planet tour. The final leg of the journey, the transport they are traveling in is attacked and destroyed. Gwen and her father's escape pod crash lands in a forrest on an under developed planet. Her mother's pod lands on the opposite side of the planet. Gwen watches her father turn into an almost ferril animal as they are not being saught for rescue, but for elimination.
With no weapons but a carving knife, a fork, and a pointed stick, Gwen watches her father kill four armed and armoured troopers. She finds out that not only is her dad actually a soldier, but he is the legendary Ghost and her mother the Zebra. For the next two years, Gwen not only learns to survive, but she and the young freinds they have collected on the planet, become deadly efficiant, skilled and feared killers of men.
