It's worth reading, very much so. Just through one chapter, the only chapter, they start, and stop what most would make into whole series... simply because the topic is a heavy one. These people brilliantly grasped it though. The emotions in it are mixed, there's a sense of will power, duty, and the fear of extinction.
(and yes, this IS my first review and i know it's bad but... there you go ^_^")
