The Loneliness of a Grim Reaper

What begins but has no end, yet ends all that begins?Your answer should be death.I am a grim reaper who has a curse of invisibility. I can speak, but no one hears me. I can move but no one sees me. For eternity I reflect on my actions of taking the lives of men. I have no ill will, yet I am tasked with this very job. Will I be able to talk to the very beings that live and breath a very social environment?I am writing this and need heavy guidance on where to go with it. I don't have very many ideas for this book. If you want to spare the life of this book, please feed it ideas.
