"It's dangerous to stay with them. It's dangerous to talk about them. Never say a bad thing about them. Never look them in the eyes." That's what every parent says to their children. The evil sisters, Beatrix and Zoelle Abigor. Even their last name means evil. But they weren't always this way. Not before their parents died. The thing is that they hid a dark secret which haunts the sisters day by day. Nobody knows anything about them, except they're trouble. The sisters have no one except each other. But maybe that will change after Beatrix and Zoelle meet Cade Walker and Xander Carter.
