Holly Winter's Alaskan malamutes, Rowdy and Kimi, are as sweetly rambunctious as ever, and her cookbook-in-progress - tentatively titled A Hundred and One Ways to Cook Liver - is really coming along. But everything else is a mess. A recent concussion has robbed her of much-needed sleep - and a failed relationship has left her with a bitter, broken heart. And her incredibly overpriced therapy sessions with the improbably named Dr. Vee Foote aren't helping one tiny bit.

It's not long before her friend Ceci stumbles on a seemingly perfect solution - and takes Holly to a park that's literally running over with gorgeous dogs. But the sight of so many leash-less canines makes Holly uneasy - especially after an aggressive golden retriever attacks her beloved Rowdy. And when one of the owners is found murdered, Holly has no choice but to step into the fray - for she knows better than anyone that killers are a cunning, clever breed.
