Honestly, I loved this issue even before the gratuitous plug for libraries and librarians. Ryan North says that librarians and librarians are both awesome. And he's right! They are awesome! And so is The Unbeatable Squirrel Girl, which, I'm happy to note, is proudly available in the library I work at.
In all seriousness, this is a great comic. North's scripts are hilarious and well-matched by the artwork of Erica Henderson and Rico Renzi. If you like good comics, you should be reading The Unbeatable Squirrel Girl.
