The Long Earth Series is a collaborative fantasy series with science fiction elements written by Terry Pratchett and Stephen Baxter. There are five books in total, which explore a series of parallel and possibly infinite worlds, similar to our own Earth.

Each of these worlds can be reached by using a simple device called a Stepper. The planets closest to Earth are the most similar, while those further away have starker differences. However, all of them share one thing in common; there are, and never have been, any Homosapiens. 

The books follow the story of Joshua Valienté, a natural Stepper, and his counterpart Lobsang. According to his own accounts, Lobsang was once a motorcycle repairman from Tibet until he was reincarnated as artificial intelligence. The two head out on a long and dangerous adventure to chart these parallel worlds and learn about the mysteries they contain. 

Conclusion

The best part about reading a series is that once you’ve finished the first book, you don’t have to mourn its loss; there are plenty more to read, and there’s no need to wait.
