Edwin's non-Transformation

Normally in novels, the main character changes in some way. Not in Happiness. At the beginning of the book, Edwin was a cold man that only looked out for one person. He couldn't care less if he lost his job, and clearly didn't care what other people thought about him based on his work ethic. I thought that his transformation was about to start when he promised he had a book ready for Mr. Mead at a meeting, then went back to his desk and it was gone. He looked for the book constantly and it was the first time, in the book at least, that he actually cared about anything.

He almost went completely back to the careless Edwin when the alcohol and tobacco mob was after him. He had the week to change Mr. Mead's mind and get What I Learned on the Mountain off the shelves. He never put forth a valiant effort towards Mr. Mead and with one or two days left he really didn't care that he was going to die. But then the men spared his life and he slowly went back to giving a crap about what he did. But of coarse, at the end of the book Edwin showed that he doesn't care. I think if he would have transformed at all in the novel, he would have shown it twice when May walked away and he did nothing.
