Product Description
Terry Pratchett & Stephen Baxter: The Long Earth (5 Book Collection)
The Long Earth is a name given to a possibly infinite series of parallel worlds that are similar to Earth, which can be reached using an inexpensive device called a Stepper. The "close" worlds are almost identical to Earth (referred to as Datum Earth), while others differ radically. Despite this they all share one similarity: on none are there or have there ever been humans — although some are inhabited by earlier hominid species such as Homo habilis.
The books explore the theme of how humanity might develop when freed from resource constraints: one example Pratchett has cited is that wars result from lack of land, and he was curious as to what would happen if there was no shortage of land or other resources.
