The Crivabanian : Odan Terridor Trilogy: Book Two

Gaedyen has vanished. The stone has been stolen. And nightmares continue to plague Enzi. But all that’s nothing compared to the coming battle.
Alone, abandoned, and out of options, Enzi must decide if she can trust the Crivabanians—a squirrel-like race who want her out of their realm. Struggling to keep her presence a secret, she develops an unlikely friendship with Veri, the sarcastically witty apprentice to the local healer.
When she overhears earth-shattering news about herself, she can wait no longer. She must seek the truth for herself, with or without Gaedyen.
But Enzi wages war in her own mind, fighting to break down the wall preventing her from mastering her power of invisibility. Legends of the great Cathawyr race and a diabolical weapon ripple to life in this riveting sequel to The Gwythienian.
