It's been a long, long time since I've seen a series like Husk of Eden, and I definitely have high hopes for it.
This is definitely a work that doesn't pull its punches, and I cannot think of a single manga in recently memory that has a death count quite like this one. Husk of Eden doesn't play it safe; in fact, it plays it patently unsafe, with the amount of well-developed characters being killed off. No one has plot armor in this work. The brutality of war leaves none untouched. Everyone is susceptible to death.
And the best part? The survivors actually feel the consequences. There is real, tangible grieving in this manga! Real mourning! People don't simply write off someone's death, nor do they simply cry a bit and then resolve for REVENGE or whatever plot device people are writing about these days. They actually suffer through the sadness and the pain of losing someone, of losing comrades they have learned to like and trust, of the fear of their own impending death, of the guilt of remaining alive.
This, my friends, is a manga that makes these deaths mean something. It makes the consequences of war, the horror of dying, so real that I cannot do anything but applaud.
This series is a true gem, and reading it is, undoubtedly, worth it.
edit: Well, so, uh, that ending happened. Unfortunately, it seems as if the mangaka ran out of steam near the end of this, and the final chapters are rushed not only storywise but also artwise. (There are pages upon pages with no background art, reminds me of Iwaaki's Historie magazine chapters, honestly.) I have no idea what real-life circumstance could've happened to lead to this, but it is slightly disappointing for a series that had such a strong beginning. Regardless, the early chapters are good enough that I don't regret reading this at all. I hope the author manages to come back to this someday, because I really would love to see how this series would've concluded if given the ability.
