Two days after being hired by the Clark County Sheriff's Department Rhonda Pohs finds herself smack dab in the middle of a murder committed in Red Rock Canyon just outside of Las Vegas. Her investigation leads her to other murders in Nevada to say nothing of other states including her home state of Wisconsin. To solve this mystery, Rhonda must dig deep into the history of the ancient Native Americans who left behind the petroglyphs and rock paintings that seem to draw this killer like a magnet. With the help of her new partner Jenny Sims and her old partner Phil Mason, Rhonda is finally able to bring a mass murderer to justice.
