Alone on an isolated farm since her partner's death, Beth lives by her own rules. When she senses that she is being hunted, she searches out the predator, turning the tables on him in an unsettling and violent climax.
Just finished this really so a full review to come, but this is the second book featuring synaesthesia suffering DCI Mark Lapslie, although if you missed the first book that shouldn't matter - there's a lot of information built into the narrative about Lapslie's background and condition.
