Not horrible, but sort of annoying. Two people pull over to try and help people lost in a field of tall grass. Madness ensues, and, of course, they can’t get out of the grass once they get in the grass.
It’s like Day of the Triffids meets Children of the Corn. But both of those others stories are better.
I liked the ending (apart from the goofy tag, which I think could have been accomplished with one sentence), but the rest of it … I don’t know. I didn’t get into these people. I didn’t really care. I was mostly bored by this. Even for a short read, it felt like work.
