Wyvernhail is the story of Hai - the mongrel daughter of the Falcon Darien and Zane's older brother, Anjay - putting her in line for the Cobriana throne (though crippled and powerless).

When Hai's cousin, Oliza Shardae Cobriana, abdicates the throne of Wyvern's Court, Hai has visions only of destruction: the serpiente king Salem, dying in her arms; the dutiful falcon guard, Nicias, unable to save a generation of children; and Wyvern's Court engulfed in flames.

The cause of this future is Keyi, the daughter of Oliza and Vere, who, after accidentally killing her mother, seems to enjoy chaos and death and brings it upon Wyvern's Court.

In order to protect the people and the world she loves from the future she sees in increasingly horrific visions, Hai is forced to throw away her own happiness and ascend the serpiente throne.

When Hai reaches for her cobra scales, she could not have it ripple across her skin, and when she tried to return to her broken falcon form, she let out a painful scream and Nicias held onto her.
