Prince Shen Teal is looking forward to seeing his annoying older brother married to the eldest daughter of the Queen of Taiwan. He's not enjoying the long sea voyage on the tall-masted European ship The Unicorn, where the food is even more nauseating than the motion of the waves. But when one day he wakes up in another World, in the body of a girl, he finds that his problems are just beginning.

When Yifan wakes up the bed is moving, and there are some nasty surprises in store for her. Dragons, tidal waves and the mysterious Dutch Captain of the Unicorn are bad enough, but when she meets an eleven-year-old Princess who has just killed her first man she realises that she doesn't know quite how dangerous her new life could become.

Prince Yifan is the second book in the Worlds of Yifan series. Yifan is a Chinese girl who lives in England with her mother and her English step-father. Her adventures in other worlds follow her as she grows up in both Western and Eastern cultures.
