The cognate Empress

Living all her life as a normal human girl from Terra, her whole world turns upside down when she is called upon to become the empress of an empire made up of eleven alien planets.
From a small office worker to a ruler of an entire race... should be the hard part, but who would have ever guessed the harder part was dealing with a new alien prince who would become her rightful mate, and who unfortunately had lived under the impression he was to be married to another.

Living all his life as the prince of an empire, his whole world turns upside down when he is forced to travel to Earth and receive the one who would take his place as the empress of the empire.
From an emperor to a consort of his own people... should be the hard part, but who would have ever guessed the harder part was dealing with a new empress who would become his rightful mate, and who unfortunately has no problem with him having another woman as his lover, even though he wished she did have a problem with it.
