What's the longest book you've ever read?

Day 35 of the 40 day book challenge is 'the longest book I have ever read'.

[image error]I'm almost certain it would be this one, A Suitable Boy.

I read it years ago and absolutely loved it, but it was hard to read because it was so heavy to hold (a Kindle would have been handy…).

There was even a warning in the front of the book that it will "strain your purse and sprain your wrists."

Have you read it?
