I really liked it. I was surprised actually because I thought it might be a little schmaltzy. I thought it was an interesting concept and he writes well.

There is a film of the book too. It stars Jon Voight as Eddie. It isn't too bad.

I have another of his books (not Tuesdays with Morrie but I cant remember its name). That was good too from memory.

ETA: Just checked. It's called For One More Day. It's (broadly) about the love between a mother and son. Good book!
