Dragon's Revenge - The Ring-Witches of Nesht, #2

Powerful Ring-Witches, Mayra and Wolfe have fled their kingdom, accompanied by their witch-warrior friends, escaping with the dragons they rescued. But once they reach the dragon's cold homeland, they find an empty Aerie. Where are the dragon females and the younglings? Barely do the witches have time to rest before they are winging their way to rescue the stolen dragons-but this one is challenging from the beginning.
The witches quickly find themselves trapped in a vast system of caverns with Hagan, an evil, fanatical dragon, and his helpers-a greedy shapeshifter and a wrathful gnome. Mayra is running out of time. If she doesn't wrest a powerful talisman from Hagan's control before he can use it, he will take control of all the noble dragons that Mayra loves. Hagan threatens to kill his hostages-the female dragons and their tiny offspring-unless Mayra allows him to collect his terrible treasure from its hiding place.
Can Mayra and Wolfe rescue the dragons-large and small-and find the talisman before Hagan and his irrational accomplices destroy all that the mighty dragons hold dearest to them? It won't be as simple as it was battling humans, for Hagan, a wielder of dark dragon magic, dares the Ring-Witches to battle him-the most savagely horrific dragon ever hatched.
