Booking through Thursday (or in this case on Saturday)

I've stumbled upon this rather cool blog, and intend to join in with mine as it fits in with my theme of books...

This week's question is:

What book would you love to be able to read again for the first time?
This is almost impossible! I wrote earlier that I can't bring myself to read the last two Barbara Pym books because I don't want to never read anything new by her again. I think it would probably be Daphne Du Maurier's Rebecca - I was so gripped when I read that (in 2003 or 4?), wondering how it would pan out. But I'd like to read the Diary of a Nobody for the first time again; how much I laughed!
