Sometimes people just...click. 'Wonderful'Kaliane Bradley, author of The Ministry of Time'A literary firecracker'Pandora Sykes, Books and Bits'Brilliant' ElleThirty-something Girlie Delmundo works a day job as a content moderator, removing the very worst that makes it on to the internet. She's one of the best at it, too, so it's no surprise when she's given a big salary rise to start moderating its new venture: virtual-reality theme parks, lush simulations of civilizations long since dead.

But as she begins to explore the intricate worlds that she moderates, Girlie notices two deeply troubling things: that there might be something much darker built into the very code of the company, and that William, technically her new boss, a man whose barriers are as mighty as her own, might just be that long-forgotten thing... Girlie's type.
