Princess Rosemary von Velfalt knows that a pandemic is imminent, so she vows to find a countermeasure. She travels to the faraway land of Flanmer in pursuit of the Khuer, a secretive tribe with the medicine she needs. There’s just one hitch—Rosemary is abducted! In a twist of fortune, her kidnapper, Wolf, turns out to be the future chief of the Khuer. However, Wolf has his own objective: he wants Rosemary to become the master of his tribe.
Meanwhile, Rosemary’s younger brother, Johan, is studying abroad. Accompanied by the two polar opposite princes of Vint, Johan visits a border town and discovers something strange. The local lord has vanished from the public eye, and his son is too eager for the royals to leave. Rumors of sickly villagers abound, despite assurances to the contrary, and it’s up to Johan to uncover the mystery.
Enigmatic assassins, malicious conspiracies, and a ticking clock… Can Rosemary and Johan come together to prevent disease from shrouding the world in doom?
