Dusty doesn't think much about it when she learns at school that a student named Skye Ryder was accidentally killed on his dirt bike. But then she finds out where he was killed (on her father's property) and how (by a cable strung across the trail). Dusty sees a picture of Skye in the newspaper that yew much resembles her horse's otherworldly new owner. And her father is drinking again. It isn't long before Skye returns: Part angel, part vengeful ghost. He will never know peace, it seems, unless Dusty can help him seek the justice he deserves, even if it means alienating the only person Dusty has left in this world.
