I just loved this audio.  Easily my favourite Nicolas Briggs script I've encountered so far.  I love the sense of atmosphere and dread Embrace the Darkness carefully builds up over the course of the story.  I also really like how it turns out nobody is really all that villainous in the story - the dark beings and sun aliens all are just trying to exist and it is really touching when the two beings are reunited at the end of the story.
