The War of the Worlds is a science fiction novel by English author H. G. Wells first serialised in 1897 in the UK by Pearson's Magazine and in the US by Cosmopolitan magazine. The novel's first appearance in hardcover was in 1898 from publisher William Heinemann of London. Written between 1895 and 1897, it is one of the earliest stories that detail a conflict between mankind and an extraterrestrial race. The novel is the first-person narrative of both an unnamed protagonist in Surrey and of his younger brother in London as southern England is invaded by Martians. The novel is one of the most commented-on works in the science fiction canon.

The Time Machine is a science fiction novel by H. G. Wells, published in 1895 and written as a frame narrative. Wells 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 backward in time. The term "time machine", coined by Wells, is now almost universally used to refer to such a vehicle. The Time Machine has been adapted into three feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It has also indirectly inspired many more works of fiction in many media productions.
