Never play cat and mouse with a saber-tooth tiger. When Kale Andrews gets disturbing mail from an obsessed fan, his brother drags him to Shifter Protection Specialists, Inc. Kale reluctantly agrees to have a bodyguard, but when a tall, muscular blond walks into the office emanating power and a sexy dose of danger, Kale's doubts about needing the man with him twenty-four hours a day quickly disappear. The easy babysitting job Aleksi was promised quickly changes from strange mail to threatening deliveries, so Aleksi has to become creative to keep his protectee out of danger. Everyone knows models are self-centered and shallow, so why does being with Kale make him feel like he finally has a home? Since he's a saber-tooth tiger and naturally dominant, most people aren't strong enough to be with him in a relationship or even as a friend. Yet Kale seems to calm his beast, simultaneously exciting the man in Aleksi. Neither man expects nor wants a relationship with strings, but as they grow closer, Aleksi realizes that Kale might be his mate. With an obsessed fan escalating toward murder, Aleksi isn't sure that even his tiger can keep his mate safe.
