The Time Machine

Probably the most influential time travel novel ever. Not only in terms of going on a ride to a distant time but also in terms of its sociological aspect.

Imagining what human beings could look like hundred of thousands of years ahead, opened so many gates of human speculation.

It also made traveling through some sort of device a popular idea, which later became the de facto item for time traveling in pop culture.

I revisited this book after so many years (read it on my teenage years) and this time did not enjoy it quite much as I expected (or remembered) , but I will probably read it again some time in the future.
