Last Days of an Immortal

In the distant future, Elijah is a member of the "Philosophical Police," who must solve conflicts that arise out of ignorance of the Other. Two species are fighting a war with roots in a crime committed centuries ago, and Elijah must solve the crime and bring peace between their species, while also confronting his own immortality in a world where science provides access to eternal life. In a world where death no longer exists, why do so many want to give up on life?
