Oath Breaker (novel)

Plot summary

While guarding the Seal Islands against the Soul Eaters for fear of them trying to take the last part of the Fire Opal, Bale asks Torak for his permission to take Renn for his mate, which makes Torak angry. Later, Bale is murdered by Thiazzi the Oak Mage, who then takes the last fragment of the fire opal. Torak vows to avenge Bale's death, and with Renn, Wolf and Fin-Kedinn follows Thiazzi into the Deep Forest where the Forest Horse and Auroch (sic) Clans are at war. As Torak, Renn and Fin-Kedinn are about to enter the Deep Forest, Fin-Kedinn is injured and turns back. Torak and Renn discover that Thiazzi is controlling the Deep Forest clans by impersonating their mages. A forest fire takes hold and Torak and Renn are separated. Torak finds his way to Thiazzi, while Renn is taken by the Deep Forest tribe. She defies the tribe and their belief that women can't be mages, by insisting that she is a mage and showing them her bond with Wolf and the ravens, Rip and Rek. She is then kidnapped by Thiazzi and imprisoned in a giant, hollow tree, where she cuts herself free in time to avoid choking on smoke. She climbs to the top, from where she sees Torak fighting Thiazzi. She throws a burning brand of wood to Torak, and a burning ember sets fire to Thiazzi's hair. He falls to his death as Eostra's eagle owl snatches the fire opal from the Oak Mage. Many months later, Wolf and his mate Darkfur show Torak and Renn their new cubs. Torak finds out that the war with the Soul Eaters is not over and he will battle the last in the sixth book.
