Tenebra is making his move. The vampire's goal is to place his son on the throne of Misthalin, unleashing a horde of the undead on the human kingdom. Once he crosses the River Sale, none can stop him. His son is Gar'rth – half-warewolf ad hero of te Siege of Falador. Should Gar'rth lose the struggle with his dark side, not even his closest allies-Kara Meir, the knight Theodore, and the wizard Castimir – will be able to save him. But it may not be Tenebra who controls Gar'rth. For Vanescula, daughter of the vampire Lord Draken, has her own plans. As war erupts, no one knows her true allegiance. Set in the world of RuneScape – the world's most popular free online role-playing game.
