Fan post apo, after reading the reviews and the preface, it Ravage made me want to read it. And frankly I have not hooked, I finished because I had paid, but what a disappointment. The book begins as a fair to good ideas, moultes descriptions of inventions of the future, we Barjavel plant the décor and even beyond, unfortunately this has not aged well and quickly becomes boring, well the book is written in 1943. But in anticipation, I have more the feeling that we wanted to fill their eyes rather than as a credible world, I not explain that he imagined that in 2050 and wheelbarrows, People extasieraient front of the waltz of the 1920s, and other examples such as farmers prefer to plow without a machine, etc ... But all is forgivable if there is a little background, but no, the characters are just caricatures, the main character is a Mercenary sensibility, nothing human sweat does him, his girlfriend Blanchette, venal, shallow with IQ of an oyster, just useful for reproduction, together with a nickname heifer ... Chaos ensues, it is rather well detailed on the first, but it quickly becomes strange, people jostle trample down the stairs but the next day, not even the trace of a body (), and occurs fire, a supernatural fire, almost divine is limited if the rock does not melt in its path. And the conclusion, a perfect world, where humans live happily no longer reproduce the mistakes of the past, the middle ages but also cool because even the ugly and misshapen will get a husband, yeah, must give its person for replanting the land ... My worst reading for quite some time, if I had not read "The night of time" before this one, I would have scratched Barjavel authors to read.
