Lady Aurelia Veyne has already saved the empire once. No one remembers.

At twenty-six, the empire’s most feared knight is executed for the crime she did commit: murdering Crown Prince Caelan, the man she had sworn to protect with her own life.

Aurelia awakens nine years in the past.

Her family is alive. The empire has not yet fallen. And Caelan, infuriatingly handsome and very much alive, does not fear her.

Armed with memories of a future drenched in blood, Aurelia intends to prevent every tragedy before it begins. There is only one problem: seventeen-year-old Lady Aurelia is supposed to be a perfectly respectable duke’s daughter, and so she intends to live up to that image.

But the future refuses to play along.

Disasters she prevents occur anyway. History begins contradicting itself. And beneath an empire founded by seven ancient crowns, Aurelia discovers traces of something that should not exist.

An eighth.
