Sir Una Everlasting was Dominion’s greatest hero: the orphaned girl who became a knight, then died for queen and country. Her legend lives on, but her life as it truly happened has been long forgotten. Centuries later, Owen Mallory – failed soldier, struggling scholar – falls in love with her tale. It takes him to war, to the archives and then into the past itself. So Una and Owen become tangled, bound to retell her story over and over, no matter what it costs. But their tale always ends the same way. If they want to rewrite Una’s legend, and finally engineer a new ending, they’ll have to confront its author – and change history itself.
