Surrounded by the hate-filled gazes of her people, Mia, the selfish princess of the fallen Tearmoon Empire, takes one last look at the bleeding sun before the guillotine's blade falls... Only to wake back up as a twelve-year-old! With time rewound and a second chance at life dropped into her lap, she sets out to right the countless wrongs that plague the ailing empire. Lazy, selfish, and a complete coward, the ill-equipped princess of the Tearmoon Empire, armed with memories of her past life and a diary from the future, tries to avoid dying at the guillotine again and changes the very course of history in the process!

Half a year has passed since the Remno revolution ended. Spring has rolled around again, bringing with it one of Mia's favorite occasions--spring break. Freed from the duties of school and station, she's ready to seize the day! By which she means, of course, do absolutely nothing productive and lounge around in bed all day. Her indolent plans are cut short when her granddaughter, Bel, is whisked backwards through time and deposited in front of her. Just when she thought she was finally done with worrying about the guillotine, she learns of the grisly future awaiting her in which a war of succession will rend the empire in two. Mia herself has been killed by poison, and Bel narrowly avoided execution by leaping through time.
