This is a great story, but...
There's always a but, and in this case it's the editing that's the problem. Using the word 'felled' instead of falling, or fell, does not show promise. The language is sometimes stilted, and the punctuation, in places, is quite odd.
Having said all that, the redeeming feature is that Blind Sight really is a great story, and for that reason, much can be forgiven. It's well worth trying to read around the inconsistencies, the story is worth the effort.
