Babylon's Ashes

This series is monumental. The world building is absolutely fantastic. When reading you get a real sense of what a colonized solar system (and beyond) would run, look and feel like. Every detail is covered: how various degrees of gravity affects things; how water, air and hydroponics provide survival, the struggle to maintain them and the impact of their loss. It's all so well constructed and real. Within this expansive universe and all the huge political and economic events are tons of great characters that are brilliantly fleshed out by changing narrators every chapter. I love it all.
