Holt Cook was not supposed to become a Rider and ride the skies on a dragon. He faithfully served the Order of Craig, working in the kitchen. That was until he learned a terrible secret: dragons do not tolerate weakness among their relatives and kill those they consider defective. Moved by pity and compassion, Holt saves the egg that hatches the blind dragon and vows to protect it. But the Riders are in danger. They are being killed. Hordes of undead roam the earth, spreading infection and leaving devastation in their wake. The traitor is nearby, but hiding in the shadows...Holt has only one chance to survive - he must revive the mysterious power of his dragon. This energy will help him tip the scales in the coming battles and prove to the world that he is worthy of being a Horseman.
