I have really enjoyed the first five books in this thoroughly enjoyable space opera series set in a near future solar system where mankind has expanded out to the asteroid belt between Earth and Mars. The hardy "Belters" who inhabit the various ships and stations in the belt are fiercely independent and live by their wits but they have long been exploited by the United Nations of Earth and the independent planet of Mars who use their military might to keep the Belters down. Earth and Mars themselves maintain an uneasy peace always just one mishap away from deteriorating into war. The Expanse has recently been made into a TV series by SyFy. The series is well made and very faithful to the books so far which is great if you are a fan of the novels but perhaps confusing to those who are less familiar with them.
By the way James S.A Corey is actually two people: Daniel Abraham and Ty Frank writing in collaboration.
