You Left Me to Die. I Became Your Reaper.

Three years after dying alone, Caelan Vale serves as a reaper, guiding souls into the afterlife. His final assignment reunites him with the family and fiancée who abandoned him for his scheming brother. Even in death, they blame Caelan, until a supernatural tribunal exposes the lies that destroyed him. As guilt and regret consume his betrayers, Caelan seeks freedom from the people he once loved. But oblivion cannot erase everything, and the memories buried deepest in his soul may reveal a destiny far greater than revenge.
