I have the last discworld novel sat on a shelf, unopened, seems I just don’t want to read it.
Same here, I’ve got the limited edition version in the slipcase, I just don’t have the heart to even take it out of the case, knowing there will never be another Tiffany Aching story. I discovered I needed to do some dusting when I got to the bit in one of the books where the bees start dancing!
There’s another book, The Wizard Of The Pigeons, which I read once, and it made such an impression that I couldn’t even pick it up, let alone read it, because the whole, rather dark story would come back. It was around thirty years before I read it again, and I’m not sure if it won’t be another thirty years before I give it another go.
