Not sure if the last one I read was "Lights Out in Wonderland" by DBC Pierre, or "Marabou Stork Nightmares" by Irvine Welsh. Both were thoroughly enjoyable, although the ending to the first one i mentioned was a bit of a disappointment compared to the rest of the book.
As for reading a book again and not enjoying it as much the second time, I've had the opposite effect from a few books, 1984 springs to mind straight away, although that's probably as I was 13 or 14 when I first read it and 27 or 28 when I read it again. The second time I read it, it f**king terrified me.
