She could enchant anyone to make her lie the truth...

Iris Holou and her two older sisters are undeniably strange. When they were young, they disappeared from a quiet street in Edinburgh, only to return a month later naked, with a crescent-shaped cut on their necks. They didn't remember anything... As if they were born that night.

Even stranger was their appearance; their blue eyes turned black like polished river stones, their dark hair turned white, with rare petals. As they grew up, strange incidents occurred in their presence. People described them as unbearably beautiful and inexplicably dangerous.

Ten years later, when Grey mysteriously disappears, Iris and Vivie follow the strange signs she leaves behind, trying to find her traces. They are not the only ones looking for her...

As they delve into the past, they realize that the story they have been told about their childhood hides the most terrifying and heartbreaking truth about their existence.
