Review of 'The Long Earth' on 'Goodreads'

3 stars

I expected a bit more considering that both authors are kind of prolific. In the end it was ok.
It obviously is only the first part of a series and suffers for it. The plot is a bit too 90s TV, although at the same time the themes of it are such that they actually do explore some areas not trodden yet.
The plot concerns the discovery and further exploration of the Long Earth, that is a line of parallel Earths that humans can travel to. These Earths are mostly identical to our Earth, except for the fact that they are devoid of humans. This becomes important because travelling to these parallel Earths turns out to be incredibly easy once one knows what to do.
Unfortunately despite being good the book still is lackluster. Somehow one would have expected either less or more exposition and exploration of the social and technological implications of this frontier.
