Isabelle Moretti has made a life for herself in New York where she can come and go as she pleases, answer to no one, and disappear into a city too crowded to pay attention to her. At least, that’s what she thinks. It starts with things small enough to dismiss. Footsteps behind her on the way home. The uncomfortable feeling of being watched. Then a photograph arrives—one she never knew was taken. Someone is watching Isabelle. And whoever it is has no intention of staying at a distance. Isabelle refuses to let a stranger frighten her out of her own life. She changes her routines, watches the street behind her, and tries to hold on to whatever normalcy she has left. Then there is Larkin Sinclair. A man she keeps running into when she least expects it. Quiet, strangely awkward around her, and suspicious enough that Isabelle knows she should keep her distance. Instead, she finds herself wanting to see him again. As the stranger watching her grows bolder, Isabelle and Larkin grow closer, blurring the line between suspicion and attraction until trusting the wrong person could become the most dangerous thing she does. Because someone has already gotten far too close.
