My rating: 4 of 5 stars
This series of books has the most interesting premise: what if you could step between infinite alternate dimensions and have the resources of an infinite number of Earths? New colonies spring up throughout the “Long Earth”, and with the aftermath of a tragedy left back on the original “Datum” Earth, people have had to move away for their own safety.
This book goes even further. Sally Linsay is contacted by her missing father, who asks her to join him on an unprecedented journey. By travelling to Mars first and then “stepping” through different versions of that planet, will they find evidence of life?
The Mars expedition is only part of this novel, but is one of the most intriguing plot lines. Back on Earth however, a new highly advanced sub-species of the human race has evolved, and is threatening to replace Homo sapiens as the dominant species on the planet. Are we going to be wiped out like the neanderthals? What other marvels await in the long expanse of multiple dimensions?
Told on a multi-global scale, but also with the focus on very personal stories and relationships, these novels are as fun as they are complex.
