The Time Machine (Paperback)
"The Time Machine is a science fiction novella by H. G. Wells, published in 1895 and written as a frame narrative. The work is generally credited with the popularization of the concept of time travel by using a vehicle that allows an operator to travel purposely and selectively forwards or backwards in time. The term "time machine", coined by Wells, is now almost universally used to refer to such a vehicle."
