Mira Valariel is the only rightful Valariel Princess, but when she was seven years old, another girl showed up, saying she was the true princess, switched at birth by a wet nurse. Even after a stone ritual where only those of Valariel blood can cause the stone to light up, the King and Queen refused to admit they had been tricked. Instead, they decreed that they had two daughters. Whichever daughter has a child first will become the new Queen of the Kingdom and rule over the five realms: Spirit, Air, Water, Fire, and Earth. On her 18th birthday, Mira has to choose her future husband. Her choices for a husband are the next in line for emperor of the Fire, Earth, Air, and Water realms. Despite her sister trying to sabotage her life, Mira is hopeful she can find the right fit. It's up to Mira to outsmart the imposter and set a new course for her future that no one can predict.
