In a future dystopian world, far into the future, there exists two classes, the saved and the errors. Saved referring to the consciousness being preserved in the system to live on after their death and the errors dying when death comes for them. I love that the novel features a diverse range of characters. The characters are multidimensional, especially the main characters. The author is successful in world building which allows us to imagine the world in which our characters live in. The story is interesting enough that once you pick it up, you won't want to put it down.
I didn't like that the features of the characters were not initially explained. For a while I went about thinking they had dyed their hair. I also felt there were some gaps in the story such as the back story of the rebel group. An overall engaging and fast-paced read.
