This is another case in which I'm donating an item that I haven't reviewed... because while I certainly paged through it and laughed like a loon, the contents of Grumpy Cat: A Grumpy Book don't really allow for any sort of thoughtful review.
NUTSHELL: If you enjoy the Grumpy Cat meme, you'll enjoy the book, if you don't, it'll just make you grumpy.
Anyway, while it made me (and Josh, who flipped through it as well) laugh, it's not the sort of book that has a whole lot of re-read potential.
I suspect, though, that it'll have a happy (or, well, satisfyingly grumpy) home in the YA section of the library.
*In case you missed it, I took over the running of my town library last week, and every day that I've worked, I've donated a book. For instance.
