What this book is about
A company's DNA testing can identify each person's perfect genetic match with complete certainty. Five interconnected stories follow people acting on this certainty: a politician whose match threatens her career, a widower navigating new love, a young woman matched with someone across the world — and a serial killer whose match doesn't know who he is. John Marrs's dark thriller is twisty, psychologically disturbing in its best storylines, and relentlessly compelling.
