On the back of the book some reviewers praise the complexity of the book. I think you can get the best out of the book, if you sweep over it and grasp the humour of the situation. Basically it is a very, very funny book. Just the idea of a human turning into a huge breast, strapped onto a hospital bed is crazy. I can't call it sexy, allthough there are some moments of strange or bizarre excitment.
Of course if you look into it a little deeper, you will see how expertly the author worked out the psychology of the breast-patient. Also the abundance with which the human, or actually the male, mind thinks of only one thing. And when he suppresses that one thing he goes straight into madness. The relationships that evolve, or actually don't, are a funny but realistic reflection of the beauty of the human soul. Well, you can get a lot of meaning out if this little book. If you still want to go deeper, be my guest or read Kafka's transformation. At least you won't be sitting in that awfully bright hospital-room.
