There’s a PBS made for TV movie about this story too, don’t know if it can still be found on streaming:

I’ve owned a copy for a while now. This might just be the push I needed to pick it up.

I read the whole book over a long weekend, I just couldn't put it down.

Make sure you don't have any work deadlines in the few days after you start it.

The first time I read it I could not put it down. Incredible book.
