The Tearmoon Empire is ravaged by revolution; its imperial family deposed, imprisoned, and executed. After years of squalid imprisonment, Princess Mia meets her fate at the guillotine. She reawakens in her twelve-year-old body with a mysterious journal.

Seeking desperately to avoid a gruesome fate, Mia begins seeking allies to help her alleviate the problems that tear the empire apart in the future. To do so, she seeks out a dour four-eyed nerd mentioned in the mysterious journal.

Princess Mia has arrived at the prestigious Saint Noel Academy. Still desperate to avoid the guillotine, she decides to avoid individuals that might contribute to that fate. However, her reputation precedes her, piquing the curiosity of her peers.

The ball is upon her, and Princess Mia's preparations have gone swimmingly. However, her dress and makeup unexpectedly being ruined completely throws off her plans. One of the nobles falls victim to an imperial kidnapping plot.

Ever vigilant to find new means of self-preservation, Princess Mia joins the equestrian club. As the academy's sword fighting tournament approaches, Mia finds herself wrapped up in a student tradition. She needs all the help she can get with it.

Keithwood rushes to prevent Mia, Chloe, Tiona, and their attendants from ruining lunch with their blatant incompetence. Then, as the tournament approaches, Prince Abel finds himself facing opponents he's desperate to overcome to prove his worth.

Back home during a school break, Mia refocuses her efforts on the Tearmoon Empire's issues within its borders. She uses her school connections to procure resources and does everything in her power to avoid an upcoming conflict.

Princess Mia returns to the forest with Dion to recover her hairpin and finds herself thrust into negotiations with the chief of the Lulus. Afterwards, she takes steps to properly secure the support of the Ruldovon family.

Princess Mia's excitement to be back at Saint Noel Academy is cut short when word of a revolution in the Kingdom of Remno reaches her and her classmates. Concerned for Prince Abel, Mia and her friends plan to sneak into Remno to look for him.

As Princess Mia and Prince Sion move to rendezvous with their friends, Mia is kidnapped and separated from her last ally. While in revolutionary custody, she'll find a new ally and learn that things may not be as they seem with Remno's rebels.

Mia and Sion finally reunite with Prince Abel. However, the circumstances are far from happy as Sion quickly challenges Abel to a duel for his loyalty to an oppressive royal authority! Will Mia's pleas be enough to prevent bloodshed?
