The Despised Black Dragon Is the True Queen

Serafina is the true gold dragon princess, cursed black at birth when Ravenna murders Queen Marina, raised in scorn on Black Dragon Island. At court she keeps saving the kingdom while Princess Leyla steals credit with a fake gold potion. Battle after battle cracks the curse, exposing Leyla's fraud. Ravenna frames Black Dragon Island for treason, but Serafina survives, breaks the curse, crushes a Northern invasion, reunites with her father, and is crowned Queen after Ravenna's execution.
