The first (British) edition of this novel gives the title as two words: Star Begotten. The title is hyphenated in the first U.S. edition: Star-Begotten.
The book readdresses the idea of the existence of Martians, famously written about in The War of the Worlds (1898). The dialogue of Star-Begotten makes brief and cursory references Wells's earlier novel The War of the Worlds, referring to it as having been written by "Jules Verne, Conan Doyle, one of those fellows".
Plot introduction 
The protagonist of the story Joseph Davis, who is an author of popular histories, becomes overtaken with suspicion that he and his family have already been exposed and are starting to change.
In other works 
At the end of Sherlock Holmes's War of the Worlds, Professor Challenger indicates that the "Martians" (not really from Mars in the story) from The War of the Worlds are the same Martians from Star-Begotten, and hints at the start of the Martian alteration-program.
In Nigel Kneale's 1957 BBC television serial, and its later 1967 British science fiction movie adaptation Quatermass and the Pit (of the Professor Quatermass series), a discovery of strange fossils reveals that human evolution was altered by a dying race of Martians, in order to leave a legacy behind. This may have been inspired by the tale of HG Wells.
