But now, ten years later, seventeen-year-old Iris Hollow is doing all she can to fit in and graduate high school on time–something her two famously glamourous globe-trotting older sisters, Grey and Vivi, never managed to do. But when Grey goes missing without a trace, leaving behind bizarre clues as to what might have happened, Iris and Vivi are left to trace her last few days. They aren’t the only ones looking for her though. As they brush against the supernatural they realize that the story they’ve been told about their past is unraveling and the world that returned them seemingly unharmed ten years ago, might just be calling them home.
