The Righteous Son. The Lost Daughters, #3

Qianfan's wishes have finally come true. After years and years of trying, the kingdom of Jinu has been blessed with a son!Jinhai, the new prince and his father's greatest joy. However, disappointment ensues when Qianfan realizes that Jinhai is nothing like him. That he's weak, emotional, and unfit to be a king. A shame to the family name. But Jinhai knows that he can become the greatest king of all, the greatest king to the people who live within the kingdom walls.
All he's ever wanted are justice and equality for everyone. And the last straw comes in the form of the abandonment of his baby sister, Xiaosheng. The only way to do that, the only way to prevent his father from destroying the kingdom with his conniving mother, is to fight and take down the king for good. But he'll need the help of his sisters, the ones his father had abandoned ages ago, betting on the hope that they'll want justice for the way they were treated just as much as he does.
With their combined powers and fury, are the siblings strong enough to take down the monster who made their lives a living hell?Or will the dictator of Jinu continue to reign supreme and destroy anyone else who comes in his way?
