Well, no, I don't, actually. It's really a rickety chair whose back I've lost any hope of support from, in a shady little Internet cafe somewhere. And I'd be completely won over by my spanking new copy of I Capture The Castle (found seven years after the library from which I first borrowed it refused to let me buy their copy- and I was too gullible to think of just snaffling it anyway), if it wasn't for the fact that it's got one of those movie tie-in covers (which is annoying, even if the movie is reportedly a nice one- I'm fussy about what my book covers look like). But I'm still rather kicked to have my very own copy at last, and still thoroughly charmed by the Mortmain family and its periphera - and I suspect I'm not the only one..
PS: Anyone attempting to place the author might find it helpful to know that she also wrote 101 Dalmatians. I remember liking the Disney movie as a kid, but the book is brilliant too.
