I was nothing. A lowly omega, destined to live in the shadows of stronger wolves. But on the night of my eighteenth birthday, the moon had other plans for me. My mate was an Alpha’s son. The problem? He wasn’t the only one. The Blackwood triplets—Kael, Ronan, and Darian—each bore the same mark that bound them to me.To be Luna, I would have to survive the chaos of three powerful mates, a jealous rival who wanted my place, and a secret buried deep in my bloodline.Because being chosen by the moon was never a gift. It was a curse.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
