His Lucky Princess Fixed It All

Chloe Shay disturbed the order of the human world. The heavens punished her by sending her down into it, with a task attached: to put the fortune of the Aetherian Empire back in order. She comes down into a family where her sister carries the memories of a life already lived and where the father takes the sister's side in everything. A marriage had been arranged. The brides are swapped, and Chloe is the one who goes to Elian Thorne, heir of the northern palace, who is known for idling. At the palace she finds every person in the household marked for a short life. Her mother-in-law and her husband's younger sister take her side. The grandmother who runs the family has decided otherwise, and so has the sister who came back. What Chloe has to work with is the power over luck she had before she was sent down.
