Trail of Destruction by Tracy Buchanan

Eager for distraction in the aftermath of her messy divorce, Ellie Mileham dives into moderating the petty squabbles on her local Facebook group. When a prankster starts trolling uptight members, it’s a welcome diversion at first. But then the war of words moves onto the streets of Forest Grove, with threatening letters escalating into violent destruction. It’s suddenly clear there’s something much more dangerous at play.

With lives at risk, Ellie delves into the history of Forest Grove and realises the so-called rural paradise has a dark and sinister heart. As she pieces together the puzzle of her own troubled childhood on the edge of the forest, Ellie learns this is not the first time the villagers have been targeted by an anonymous vigilante with an axe to grind…

Could the two cases be connected? Ellie is determined to find out. But with everybody watching and nobody quite what they seem, can she uncover the truth before online threats become nightmarish reality?
