Amber Blackwood, lifelong resident of Edgehill, Oregon, has earned a reputation for being a semi-reclusive odd duck. Her store, The Quirky Whisker, is full of curiosities, from extremely potent sleepy teas and ever-burning candles to kids' toys that seem to run endlessly without the aid of batteries. The people of Edgehill think of the Quirky Whisker as an integral part of their feline-obsessed town, but most give Amber herself a wide berth. Amber prefers it that way; it keeps her secret safe. But that secret is thrown into jeopardy when Amber's friend Melanie is found dead, a vial of headache tonic from Amber's store clutched in her hand.
