The Lord-Protector's Daughter is a standalone fantasy novel that takes place in Tempre, the capital city of Lanachrona on Corus, the world of Modesitt's Corean Chronicles.

Mykella, the eldest daughter of the Lord-Protector of Lanachrona, discovers that someone is diverting significant sums of money from her father's treasury. One of the ancient soarers appears to Mykella, telling her that she must go to the antique stone Table in the cellars of the Palace and find her Talent in order to save her land and her world.

From there, matters become more perilous. There are attempts to remove Mykella and her sisters from Tempre by marrying them off to lords in neighboring lands, and fatal and near fatal accidents occur to members of her family and trusted retainers. While Mykella develops a solid idea of who stands behind it all, every attempted solution is used to discredit her. How can she save their father and land?
