The Time Machine (SF Masterwrdes)

At first, the future looks like an enchanting place to the Time Traveller. The graceful Eloi appear to embody contentment, beauty and peace, and the Eden they live in seems to be free of suffering. But he soon comes to understand that the Eloi are fragile creatures, desperately afraid of the dark, and with good reason. For the Morlocks live in the dark, and the Morlocks are to be feared. And the Time Traveller must venture into their subterranean world to find his way back to his own era.
