Seventeen-year-old Cassel seems to be the only untalented one in his family of curse workers – he has, however, perfected the art of the con, which he relies on to convince his classmates that he is normal. But a strange white cat keeps appearing in his dreams and making Cassel think about his friend Lila, who he killed years ago. When he sleepwalks onto the roof of his school, he is suspended and ends up back in his family home – where the same white cat which had been in his dreams appears. What is the connection? And can Cassel out-con the conmen?
