After a scandalous arrest in San Francisco, Carissa Carmichael has moved back to her small Southern California hometown to start over as she opens her Aromatherapy Apothecary shop and reflexology services. A tourist destination, Oak Creek Valley seems the perfect place to put the past behind her, but it seems no one will let her forget, especially her high school nemesis, Lacie. When Carissa finds her frenemy murdered after having a public altercation at the town's playwright conference and festival, she becomes the primary suspect. It doesn't help that the tarot cards she drew earlier in the day foretold the nature of the murder weapon. Despite her father's position as Oak Creek Valley's chief of police, the detective assigned to the case assumes she's guilty.

When tarot death cards begin turning up to taunt her, Carissa not only has to prove her innocence to keep her freedom, she has to make sure death doesn't come calling for her or those she loves. With the suspects acting as slippery as the essential oils she distills, it's up to Carissa to apply pressure and sniff out the truth before it's too late.
