Master of Dragons is the epic conclusion of Margaret Weis's triumphant Dragonvarld trilogy, an epic of politics, war, and the delicate balance of the ways of dragons and men.

From Publisher's Weekly:
With a bright flash of dragon magic, bestseller Weis winds up her enchanting Dragonvarld trilogy, which began with Mistress of Dragons (2003) and continued with The Dragon's Son (2004). Nasty rogue dragons have plunged this colorful fantasy world into turmoil. Ven, who's part dragon and part human, and his normal-appearing twin, Prince Marcus, seek to avenge their mother Melisande's brutal death. Marcus also hopes to protect Idylswylde, his father's kingdom, aided by the gypsy Evelina, who longs to trap Marcus into marriage and ends up holding the key to future dragon intrigues. A fire-breathing finale leads to a mysterious denouement that hints of adventures to come. Weis is also the co-creator with Tracy Hickman of the Dragonlance role-playing game series.

From Booklist:
The conclusion of Weis' compelling Dragonvold trilogy is an eminently fitting companion to Mistress of Dragons (2003) and Dragon's Son (2004). The trilogy's two renegade dragons have assumed human form by ripping the hearts out of living humans and taking over the bodies in a horrific plot to enslave humanity and rule dragonkind itself. Meanwhile, the twins, one of whom was sired by the dragon Grald in human form, have grown up and discovered each other, and while the fully human Marcus works to come into his dragon powers, his brother, Ven, who walks on dragon legs, denies his own powers. But it will take both of them as well as their mentor, Draconas, the dragon who walks in human form, to confront and defeat the evildoers. Weis spreads her net wide, bringing together the disparate plot threads of the previous books to wrap things up in a satisfactory manner and yet allow room, perhaps, for another story set in the same world.
