A woman's suspicions about her ex-boyfriend become a dangerous obsession in a twisting novel of psychological suspense by Washington Post and Wall Street Journal bestselling author Minka Kent. Eight years ago, Grace McMullen broke Sutton Whitlock's heart when she walked away. But it was only to save him from the baggage of her own troubled past. Now all she wants is to make sure he's okay. Only everything she learns about him online says otherwise. According to his social media accounts, he placed roots in her hometown, married a look-alike, and even named his daughter Grace. He clearly hasn't moved on. In fact, it's creepy. So Grace does what any concerned ex-girlfriend would do: she moves home...and watches him. But when Grace crosses paths with Sutton's wife, Campbell, an unexpected friendship develops. Campbell has no idea whom she's inviting into her life. As the women grow closer, it becomes clear to Grace that Sutton is not the sentimental man she once knew. He seems controlling, unstable, and threatening. And what a broken man like Sutton is capable of, Grace can only imagine. It's up to her to save Campbell and her baby now-but while she's been watching them, who's been watching her?
