[TOMT] [Book] Science fiction book about aliens telling humans to stop developing technology
Sorry I don't really have any more detail. I read this blurb about a book on either reddit or goodreads. Something about humanity discovering interstellar travel or something major like that and aliens sending a message warning humanity to stop, or else. At least that's what I remember. Any help would be appreciated. Been searching for a couple of hours and have had no luck.
