Mia brings with her a bloodstained diary that confirms her memories of the future were real, filled with suffering and humiliation that will occur if nothing changes. Knowing what is to come, she must transform herself, gather allies, and use her knowledge to prevent the empire’s downfall. However, Mia is ill-suited for the challenge, but has no other option if she wants to avoid a second execution.
