How far would you go to reclaim the life you were denied? Shae Halston wears her lies like a second skin. The dutiful daughter. The perfect wife. The loving caregiver. After a lifetime of betrayal, abandonment, and unspeakable abuse, Shae has learned one truth-revenge is the only way to heal. When she takes a job caring for Kelly, a once-renowned therapist left helpless and disfigured after a tragic accident, Shae sees it as the perfect opportunity. Because Kelly isn't just her patient. She's the woman who destroyed Shae's life. As secrets unravel and memories resurface, Shae's grip on reality begins to slip. Kelly knows more than she lets on, and Shae's carefully constructed revenge spirals into something far more dangerous. In a house filled with buried secrets and ghosts of the past, the line between victim and villain begins to blur. How far will Shae go to punish the woman who left her? And what happens when the monster you're hunting... is you? Darkly twisted, chillingly intimate, and deeply unsettling, The Intruder is a psychological thriller about generational trauma, manipulation, and the darkness that festers when revenge becomes an obsession. Perfect for fans of The Locked Door by Freida McFadden, Sharp Objects by Gillian Flynn, and The Family Upstairs by Lisa Jewell, this story will haunt you long after you've turned the final page.
