Hudson Kincaid prefers the wide-open spaces. But tracking down a serial killer means hanging out in Denver as he investigates neuroscientist Dr. Marilyn Monrose. So far, he can't figure out if she's a city kitty in high heels or a country kitten in cowgirl boots. Marilyn's experiment in ramped-up virtual reality captures the final moments of each murder victim's life, a chilling discovery she's trying to keep secret. The last interruption she needs is a determined private detective barging into her lab—no matter how sexy he looks wearing his Stetson hat. When word of her research gets leaked to the press, Marilyn becomes the killer's next target. Now the woman Hudson races to save is the one who has stolen his heart.
