Oh, well the first thing I noticed is that you started out y writing about boringness. That is not an effective way to get a reader's attention, although it is cool the way you explain it. Tack another sentence onto the beginning to help explain how it inspired you. That way, the way it inspired you is something that you can clarify throughout the rest of the essay. It can come right at the start of this first paragraph:
The cover of the book does not spark nearly as much interest as the words inside. It is a bland shade of beige with a black and white photo ...
As for giving adequate background for the book, I think you do not have to worry about that... the most important thing is what the reader learns about you.
You write very well!
