Tucked in the cold Colorado mountains lies the remote village of Gray Birch, a place where outsiders are frowned upon. In this village lives a cat named Bijou. But she’s no ordinary house cat; her ancestors were mousers on Viking longships, and their blood runs through her veins. Since her battle skills are hardly needed in this modern age, however, she spends her energies running the Fox Burrow Pet Inn with her human, Spencer, and her assistant, Skunk, a mentally negligible Pomeranian. Together, the happy trio has created a safe haven for their four-legged guests.

But when Eddy Line, a handsome baker from California, comes to the inn―along with his piglet and pit bull puppy―everything changes. Spencer falls for Eddy, Bijou is unhappy with the sudden changes to her clan, and the townspeople are anything but welcoming; in fact, threats are made against Eddy when he buys the town’s historic firehouse in order to open a bakery.

Then a shocking murder/dognapping occurs on the night of the bakery’s grand opening, and Bijou finds herself thrust into a tangled mystery. To solve it, she will have to summon her inner Viking―and fight tooth and claw for her new clan.
