Opal once again dives headfirst into danger, this time without Claude! The duchess sails to Lumeon to support her friend, Princess Ellie, who will soon ascend the throne and become grand duke. Unsurprisingly, much trouble is bubbling under the surface: Ellie's cousin Mikhail is adamant that they incite a revolution to replace Lumeon's monarchy with a republic, while her uncle Eckhardt, the acting grand duke, rules the nation-and Ellie herself-with an iron fist. Not to mention that rumors that Eckhardt has hidden away a massive amount of wealth have spread like wildfire, causing the whole world to watch Lumeon in hopes of snatching such a lucrative treasure. Spies, assassins, and elites from all over the globe will stop at nothing to obtain that money for themselves.
Can Ellie overcome the hurdles that plague her nation and successfully rule over her people? Can Opal provide the support that the princess so desperately needs? And what in the world is Julian up to?
