This book hovers between the three and four star mark for me. I enjoyed My Antonia much more.
I enjoyed it, and, yet, at the end, when the Professor felt he'd rediscovered some lost younger self, I didn't believe it for a minute. He had changed, yes, but nothing that he was now feeling sounded like a younger person, it sounded like an older person who discovered he hated his life.
And so, a book about a man progressively discovering he hates his life, dislikes his wife and children and couldn't care less if he dies...was not that interesting. None of the characters, except the dead Tom Outland were likeable, including the Professor himself.
So, not one of my favourites.
