To fulfill the prophecy, Jacob must bring together two parts of the comet stone. Jacob expects his friend Orson to help, but Orson betrays him. Soon Lord Manning has both Orson and Lia under his control. On his side, Jacob has only his own courage and Draco, the fully grown dragon. But the comet returns, and magic can sometimes work miracles. Draco's Fire is a spectacular finish to the Dragon Speaker trilogy.
