Eterna

Sir Una the Eternal is the greatest heroine of the Reach. The orphan who drew the sword from the yew tree, who became a knight, who slew the last dragon, found the chalice of life, and died for the crown and the realm. Her legend lives on. Centuries later, Owen Mallory, a disgraced soldier and second-rate researcher, dedicates his life to the myth of Una the Eternal, abandoning a promising career to defend the realm. After the war, he returns broken and lost until he finds a new reason to live within the pages of a mysterious book. After traveling through time, Owen must chronicle Una's final feat and ensure she reaches her tragic end, even after meeting the complex woman behind the myth. He doesn't know if he will be able to see her die... or how many times he has already. If they want to change Una's fate, they will have to rewrite history itself.
