The Time Machine
I'm glad my first experience with Wells was such a positive one. Despite its shortness, "The Time Machine" is packed both with plot, description, as well as philosophical and self-reflective musings in one tight package. It was beautifully and chillingly visual, and terrifying due to everything it implied and proposed. I can only hope that, if I ever end up haunting the earth as a ghost after my death, it'll be a slightly less terrifying revelation that the Time Traveler's jump even further beyond, towards what may have been the last moment before the disappearance of existence itself.
