Alice is no ordinary young woman. Upon the death of her grandmother, a year earlier, a gift came to her: the ability to see the emotional attachments of every person she meets. These bonds appear to her in the form of luminous threads, creating before her eyes a veritable web between people. Unable to explain the phenomenon, Alice learns to live with it in deepest secrecy.

While her sixth sense allows her a better understanding of the world around her, she is simply unable to figure him out. And yet the attraction is irresistible…
