My Sister is the Warlord Queen

Abandoned by their parents, sisters Catherine and Grace Blackwood learned early that they could only depend on each other. Both went on to build accomplished lives of their own. But at Grace’s engagement party, Catherine shows up fresh from an undercover operation, still wearing her janitor disguise, and quickly becomes the object of mockery from Grace’s future in laws and old classmates. When Grace is betrayed and publicly shamed by her fiancé, Catherine steps forward, unveils her true identity as the feared Warlord Queen, and ensures that everyone who looked down on them pays the price.
