He figures that Kurda, working in league with the enemies of the vampires, the vampaneze, is going to betray all the vampires and the Vampire Princes and allow the vampaneze to access the Stone of Blood. With the Stone of Blood, the vampaneze will have the power to find and kill almost every vampire in the world. Darren knows he's the only one who can stop Kurda, but how will he do it?From the heart-pounding introduction through the twist at the end that brings Darren into a whole new way of vampire life, Shan never gives Darren, or the reader, a second to relax.
