For fans of fantasy literature and SF like me, everything starts as in "The Circus of Dr. Lao" Charles Finney. One night a circus arrives in a small American town. Gradually, the villagers found the funfair a bit strange but no more. Two teenagers fourteen, Jim and Will, intrepid and curious will eventually discover what hides terror that hides in the tents. This book Bradbury is not a masterpiece, as are "The Martian chronicles" or "Fahrenheit 451" but in a different genre, he turns more toward the fantastic and is a true wonder of reading. This book is not a racist and is of course not a criticism of Travellers. I do not understand certain reactions. This great writer 88 spring is with Asimov, Vance, Clarke, K. Dick and many others, a key writer. Even Dick or means Bradbury (here excellent) largely flat over many SF books. Read this book is captivating and you plunge into the fourth dimension.
