Rosemary von Velfalt wants a quiet life with her beloved Sir Leonhart, but the king has other plans; she'll be forced to marry a foreign prince unless she can prove indispensable to her country. Her quest to cement her worth leads to an expedition into the Kingdom of Flanmer—but she isn't exactly invited. Not content to be sidelined again, Rosemary boards a ship destined for a new land in search of the friends who've left her behind and a reclusive tribe with critical secrets. She vows to travel any distance for a chance at a future with Sir Leonhart, and though it'll be hard going without him, her faithful masochistic guard is always close by! Though he can't make tea, what he can make is...people uncomfortable. Disguised as a commoner, Rosemary is joined by her eccentric fellow passengers: Michael's gorgeous older sister, a flamboyant man, and a pampered brat who thinks she runs the place. As they depart for an adventure, little do they know what dangers lurk on the open ocean...
