I have to say, this is one of my all-time favorites. I've read Atkinson's "Human Croquet" and "Behind the Scenes at the Museum," and they are every bit as good as everyone says they are.
But I adore the way she takes off here -- the hilarious academic parody, the deft weaving of two or three different texts into a whole and the compelling emotional story at the core. I giggle my way through this book every time I read it, but its far better than just straight comedy. I don't even think you necessarily need to be aware of the various literary styles and methods of criticism she skewers to find the humor in the book -- her slacker undergrads are funny enough to entertain all by themselves. (Bob, the brainless Trekkie who spouts bits of philosophy in his sleep, is my favorite.)
Please read it. I really think you'll like it, especially if are or ever were an English major.
And don't be put off by the title...far as I can tell, it was picked out of a hat. Just ignore it.
