Scientist Koreas Pryde has a dilemma—she can't figure out what causes mating heat. As a lion-shifter, she’s had her fair share of run-ins with the dreaded heat, but her battery-operated boyfriend has always come to the rescue. The last thing she expects is for a human male to enter her life, turn it upside down, and render her “toys” obsolete. Austin James has to have some thick skin—it’s a must being a human at a ranch full of shifters. His time there was supposed to be relaxing, not spent wagging his non-existent tail over a sexy little scientist. But dang it all, if that isn't exactly what he finds himself doing.
