Leverticia Celsiear, a wisecracking noblewoman-turned-knight is used to taking care of herself and her younger brother. But she never expected to add the eight-year-old duke, Caius Baltail, to her protection list--until the emperor arranged their marriage. Meanwhile, she’s also got an eye on her nemesis, rival knight Anthody Everett, is tracking down the truth about her parents’ death, struggling to get out of debt, and even gets stuck in a time-distorted dimension! Whew! Good luck Leverticia! (Source: Tapas) Note: Includes eight extra chapters.
