Leviathan Wakes by James S.A. Corey

4.0

There's Earth, Mars, and Belters. You belong to one of these three, and whilst those of Earth and Mars might understand each other, they are used to having oxygen to breathe, and a sky to look up at. Belters are humans who grow up in space, and so have longer bodies.

I thought this was a really good beginning for a series of which there's quite a number of books, and a TV series!
