so it automatically loses a star for false advertising. do not put a unicorn on the cover unless there is actually a unicorn to be had. cheap shot, john green - you know i am a girl and as such, genetically inclined towards all things unicorn. but it automatically gains a star for being a free download which is a generous thing for an author to do (and this from someone who hates reading on the computer - you see what the "promise" of a unicorn will do). even though it was short, i had to read it in a couple of installments because of the yuk of reading on a computer, during one pause of which someone said to me "you know there are no unicorns in it, right??" (no, ma'am, i did not) but i continued!! 
 turns out, it is about corn. and zombies. so - zombicorn. guess that would not have made as arresting a book cover. if i know how to photoshop stuff, there would be a really cool picture here. 
 another star just for john green. i have only read one of his books, but i really liked it (even though i don't usually go for "realistic" teen fiction), and i hear such great things about his other books, and about him as a person. and did you know he was born exactly one day after me?? fact. there is something about his writing that makes me want to lay my head in his lap, but in the way a kitten would, not LGM. just like, "and tell me another story, please, john..." 
 there isn't too much to say about it except this is a great short story, with very sympathetic characters, a bizarre premise, and some sweetness and some humor along the way. it's free, dude, just read it.
