Descendants of Magic Book 2
Princess Rhea, an Elanian princess, was sent to another land by her uncle, Emperor Derek, to live a life he could not offer her. She grew up believing the people who by all standards adopted her were, in fact, her true parents, and rightfully so. When she gains magic pertaining to the winter and the light, that is when she also finds discrepancies galore.
Then she meets an angel by the name of Fayern, who helps her try to understand the story of her family and the kingdom that is her birthright as much as the man who rules it. When she eventually decides to pay her uncle a visit, everything unravels in a way she can surprisingly begin to comprehend, but there is more than a family legend waiting for her there.
