That picture you posted? I’ve seen it. That location you tagged? I’ve been there. I know everything about your life... And I’m going to destroy it. A recent transplant from sunny California, life in the London suburbs is not what Taylor Watson expected. Far from the West End shops and city lights she imagined, she finds herself pregnant and lonely, with a husband frequently away on business and only social media to keep her company. It’s only after Taylor joins a book club and a walking group, that she finally starts to make some real-life friends. Before long, Taylor’s hanging out with Anna, Sarah, Simon, and Caroline but, as her pregnancy progresses and her friendships blossom, a sense of unease develops. Nothing’s ever quite as it seems on the surface, and it soon becomes clear that Taylor’s new friends have secrets. One appears to be after Taylor’s husband, another’s always putting her down, and then there’s the question of Simon. Could he have feelings for Taylor? But far more worryingly, one of the group’s not being too careful what they post on social media—and another is watching all too closely. Who’s stalking who...and why?
