Where four kingdoms stand as bastions of power, secrets and deception flourish. Within this realm, a courageous young girl named Cassiopeia Reed yearns to join the esteemed Royal Guard, dedicated to upholding peace and order. Cassiopeia, affectionately known as Cass, grew up rather ordinary. She trained tirelessly to protect her kingdom, her best friend, the young prince Theodore Astley and his older brother, Nicholas Astley the heir to the throne. When she is suddenly faced with a shocking betrayal, that throws her whole life off course. She is forced to leave everything behind, people she once called allies, and go on a journey to uncover truths about the world and herself. She needs to get answers about the elementals - beings of extraordinary power to control a singular element. But the destiny that awaits her, is so much larger than she could ever know. Much larger than the gardener's daughter.
