A few years ago, I found a truly dreadful short story collection on Podiobooks, called All Kinds Of Things Kill. Can't, or don't want to, remember the author's name though.
One of the stories in that collection was also about razor sharp killer grass, but where that one made me cringe throughout, this one was really good.
Ta for posting it and helping me through my morning coffee.
The truth may be out there, but lies are inside your head.
