Eco-architect Olivia Wells returns from her successful life in New York to the Cornish village of Penbartha intent on fulfilling her god-father's bequest to expand and oversee a co-working community of eco and creative entrepreneurs in a converted railway building.

Opposition to her endeavours soon surfaces and it becomes clear that not everyone is committed to the cause. Then, the day after an unexpected argument with someone she considered a friend and ally, Olivia finds her murdered body.

The tight-knit Cornish community hampers police investigations and when the forensic evidence places Olivia firmly in the frame, she is persuaded to put her trust in an unlikely accomplice. Using their unique combination of skills, they work together to try to clear her name, but their sleuthing gets them caught up in a dark web of secrets and lies.

Will Olivia be able to find the killer before they make her their next target, or will this inheritance turn out to be the deadliest of all?
