Query: Great book a must for every si.fi. fan

This is the first (and only) H.G. Wells book I read. And I must say, it's great! It has an interesting look into the future.The time machine takes an interesting look at human society in the distant future. The time traveler witnesses the unbelievable social stratification of humanity into two groups. I love science-fiction and this is almost the best book I've read.I think that this book was a masterpiece that everyone should read, young or old. It was a great piece of literature that stands out from all the others because it has quality and different viewpoints to what the future might hold in store for all of the world and humanity.Around The World in Eighty DaysDick Sands the Boy CaptainEight Hundred Leagues on the AmazonThe Adventures of a Special CorrespondentThe Blockade Runners
