The Lady's Law of Survival

Story

“Please let me take over someone else’s body this time!” That was my request to the King of the Underworld upon my latest arrival. None of my previous incarnations made it past my 25th birthday, so the king promised that if I succeeded, he’ll grant me a long, healthy life. I asked for an existence filled with wealth and physical prowess that had no siblings and no complications with men… At least he fulfilled the first three! My name’s Lukina. Title: the Duke’s daughter. And my goal: survive past the age of 25!
