As the only veterinarian at Oak Falls Animal Hospital, Dr. Kate's life is complicated. Winter storms hit the Hudson Valley, she's swamped with hospital patients and house calls, and her long-distance relationship with law student Luke Gianetti is precarious.

And then Sookie Overman, a professional organizer, is found dead - and when another body is found, it's clear there's a murderer on the loose. Rumors swirl and suspicion falls on Sookie's husband. But Kate isn't convinced he's a killer, not after getting to know him while treating the family cat. Realizing she'll need more than old-fashioned hunches and sleuthing to crack the case, Kate teams up with Rainbow, a quirky hacker. But can the tech genius be trusted? Kate will have to trust her own instincts-and those of her beloved animals-to stop a killer in their tracks.
