The Guinevere deception

To keep Camelot and King Arthur safe, the great wizard Merlin conjures a plan--he takes a magical changeling and renames her Guinevere, sending her in under this disguise to marry Arthur and defend the realm with her magic. Navigating the court of Camelot proves just as dangerous as the wild magic of the forests and the black depths of the lakes seeks ever to reclaim the land. However, Guinevere herself, to herself, may be the biggest mystery of all.
