One day, the three Hollow sisters disappeared. When they came back, one month later, with no memory of where they had been, it was as if nothing had changed. Apart from the scar that had appeared in the hollow of their throats and a whispering sense that something is not quite right about them. A thrilling, twisting novel that is as seductive and glamorous as the Hollow sisters themselves. 13+ From the bestselling author of "Our Chemical Hearts".
