The society of thirteen

London, 1891. When orphans Esther and Tom are caught stealing by Lord Ringmore, little do they realise the peril they are in. Rather than hand them over to the police, the lord employs the children. But what does he really want with them? He has in his possession a book that contains the secret of true magic, but he cannot unlock its meaning alone. Only Tom and Esther can help him unravel its terrible and dangerous secrets.
