If you like science fiction with an Old West flair, you've got to read this. It's post-apocalyptic America with a "deadman" named Donovan who starts out as a postman, and ends up becoming something else, something that can give him far more opportunities to grow - or die.
Donovan was a fun character to follow. He's sensible, so he ends up making unexpected choices, a big difference from the usual hotheaded protagonists. I liked his sense of humor, and how he didn't take things at face value.
The world building was superb, and felt effortless. No infodumps, no dialog explaining how everything works, no endless descriptions. Yet, the scenes weren't hard to visualize or understand. The book overall had a very nice flow.
The structure also appealed to me. While there was an overarching story, there were sort of episodes that solved smaller mysteries along the way. While the main story is still open, the mini-stories are mostly closed. The repercussions though... can't wait to see what happens!
