Premise-wise, Everless was one of the most original books I've read in a long time. It was very intriguing, to say the least. It presented a world where life and blood are currency. I loved this idea and really enjoyed how it was integrated into the story. It was ruthless. I think the details were very well thought-out, especially when it came to how the rich exploited the poor. I also liked the legends that were incorporated and how they pulsed through the lives of the characters.
