Stella has spent years being sensible: a steady office job sorting out insurance claims at an engineering firm, a nice house, a reliable husband, and two teenage children who think she's just a boring mum.
Back in 1996, she was a firebrand eco-activist who once chained herself to the bucket of the excavator her future husband, Steve, was driving.
When a chance encounter beneath the ancient branches of the Lucky Oak reveals that the local woods are under threat from her own employer, Stella is hurled back into a world she thought she'd outgrown.
If she joins the protest, she could lose her job, her home, and maybe even her marriage.
Is standing up for nature worth risking everything?
