About The Expanse

The Expanse features a large cast of characters over the course of the nine books but largely focuses on Captain James Holden and his crew. It is set in a distant future where humanity has spread across the stars and colonized most of the solar system.

However, humanity’s spread is kept in check by the Martian Congressional Republic, another superpower in the system. A third group lives alongside the humans and Martians. Known as Belters, they are the people of the Asteroid Belt.

Throughout the course of the series, The Expanse deals with many themes such as authoritarianism, colonization, aging, science, and discovery.

Humanity continues to spread when some new and uninhabited worlds are discovered and there is a rush to colonize them and claim their land and resources. There are many wars between different races as they struggle for power.

The series takes place over several decades so the reader is able to see the personal development of each character and how the aging process affects them.

Final Thoughts

In this article, I introduced the nine main books in The Expanse series. The series starts with Leviathan Falls and ends with Leviathan Wakes, making the series complete and finished.

The series is soft-science fiction that brings in many themes that are important in modern life. It deals with colonization and wars between races, as well as the importance of science and discovery.

Through the use of a 30-year time skip between book 6 and book 7, the series is able to show both the advancement of humanity and the problems it brings to the universe.

The writers are also able to show their main characters as they age and how this affects their actions in the story.
