In this darkly seductive New York Times bestseller, three sisters discover they are not all that they seem in this twisty modern-day fairy tale by critically acclaimed author Krystal Sutherland. Now in paperback.

Iris Hollow and her two older sisters are unquestionably strange. As children, they disappeared on a Scottish city street only to return a month later with no memory of what had happened to them or where they’d been. More troubling, their appearance began to change: their blue eyes now black, their dark hair now white. And as they grew older, odd, eerie occurrences seemed to follow in their wake. People find them disturbingly intoxicating, unbearably beautiful, and inexplicably dangerous.

Now seventeen-year-old Iris is doing all she can to fit in and graduate high school on time-something her two famous, glamorous, globe-trotting older sisters, Grey and Vivi, never managed to do. But when Grey goes missing, leaving behind bizarre clues as to her whereabouts, Iris and Vivi are left to find her-but they aren’t the only ones looking. As they brush against the supernatural, Iris quickly realizes that the story she’s been told about their past is unraveling and the world that returned them seemingly unharmed ten years ago might just be calling them back again.
