It’s 2020, and Jane, a scientific illustrator, has just moved to the woods in the Driftless Area of Wisconsin. After volunteering to foster a troubled shelter dog, Jane and her new pup, Bumbershoot, stumble upon unusual hexagon-shaped mushrooms on the bark of oak trees. Jane follows her scientific instincts to investigate further, but suspicious trespassers at night and vandalism spell danger. Isolated and solitary, Jane is making risky decisions in a vacuum. Her neighbor is handsome and appealing, but what is going on in his shed at night? When she sees a dead body in the woods, Jane realizes her nosy inquiry may have gone too far. Will her relentless curiosity about the natural world help her solve the mystery of these growths, or will her meddling lead her deeper into jeopardy?
