Reading conundrum

I always worry, when going away for a few days, how many books to take. I never get it right. I'm probably here in rural Shropshire for 3-4 days, so I thought 3 biggish books should be enough. Then I went to bed at 12.30 last night thinking I'd read a few pages of Mark Radcliffe's book. 2 hours later I'd finished it. Even though it's randomly unstructured and not particularly profound (Pooterish?), Radcliffe's essential niceness shines through, so it was worth reading. So that leaves two books (Kim Stanley Robinson's The Years of Rice and Salt and J. G. Farrell's Troubles, unless I rush out to the booksellers tomorrow. Perhaps I shall.
