True, the world of Eden is ruthless and unforgiving, but the people in it are still people, with hopes and dreams, with jobs, family and all that. Most of them haven't given up on being human, being able to love and being loved, to feel, even though the world around them is full of corruption and greedy bastards for leaders. I think that in itself is a sign of hope.
And I also like the way no one is really safe. There's a character that's been around for longer than a few pages and who interacts a lot with other characters of the story. Usually this kind of character has some sort of magical life insurance that makes him/her invincible. No matter how big an explosion or intense rain of bullets, they come through virtually unscathed. In Eden, they can bite the dust anytime, just like anyone else. That makes the reader feel more involved, more shocked than usually; "that couldn't have really happened!" Keeps the reader on their toes.
