I enjoyed almost every minute of reading this book, but then, after I
finished it, I wished that she had either made it a lot longer or
introduced fewer characters. Some of the most interesting characters
disappear midway through the book, never to be seen again. I imagine
that was on purpose, but it left me feeling a bit unsatisfied.

That said, I recommend it: http://amzn.to/AVisitFromTheGoonSquad
