B.A. Paris delivers another psychological thriller that will appeal to fans of domestic suspense, though it doesn't quite reach the heights of her debut 'Behind Closed Doors.' The story follows Cass, who suffers a mental breakdown after witnessing what she believes is a murder on a dark country road. When no body is found and her husband Matthew dismisses her concerns, Cass begins questioning her own sanity as strange incidents pile up around her.

Paris excels at creating an atmosphere of creeping dread and uncertainty. The pacing is generally solid, with short chapters that propel readers forward as Cass's world unravels. The author skillfully plants seeds of doubt about the reliability of her narrator, making readers question whether Cass is experiencing genuine threats or psychological deterioration. The exploration of mental health, particularly how trauma can fragment memory and perception, feels authentic and adds emotional weight to the thriller elements.

However, the book suffers from some significant weaknesses. The supporting characters, particularly Matthew, feel underdeveloped and sometimes act in ways that serve the plot rather than feeling genuinely human. The resolution, while providing answers, relies heavily on coincidence and feels somewhat contrived. Additionally, some readers may find the portrayal of mental health issues problematic, as the line between 'crazy' and 'in danger' sometimes feels exploitative rather than sensitive.

This book is perfect for readers who enjoyed 'The Girl on the Train' or other unreliable narrator thrillers, and those who appreciate domestic suspense with psychological elements. Fans of quick, twisty reads will find plenty to enjoy. However, readers seeking complex character development or those sensitive to mental health portrayals might want to skip this one. Similarly, those who prefer their thrillers grounded in realism may be frustrated by some of the more convenient plot developments. Overall, it's a solid if not exceptional entry in the psychological thriller genre.
