A new marriage. A perfect home. A machine that says it's all a lie. Welcome to Silicon Valley, where the weather is perfect, the income is high ... and Rowena Snyder is miserable. A transplant from New York, Rowena moved into her husband Jacob's idyllic childhood home with their new baby. But suburbia isn't Rowena's cup of Starbucks. And she's got serious anxiety and depression to boot. Jacob, worried about their marriage, scores a new product currently in beta testing from his tech job: Maxine, a "digital friend" that bonds with an individual by continually gathering their personal data. Along with functioning like an upscale digital assistant, Maxine has "advice" and "prediction" modes that have shown promise for patients with mental health issues. To Rowena's shock, the device turns out to be not just helpful, but eerily accurate, predicting events before they occur. It's a godsend until Maxine offers a series of increasingly bone-chilling predictions that will change Rowena's life forever. This domestic suspense novel set in a near-future dystopia asks, who do you trust more-your mind, your man, or your machine?
