The book that’s been on your shelves the longest.
I'm not absolutely sure, but one contender would be Little Tim and the Brave Sea Captain written and illustrated by Edward Ardizzone. I've had it for as long as I can remember. There are also a couple of books of poetry that my mum used to read out loud to me. Oh, and her copy of Hans Anderson's Fairy Tales with rather beautiful illustrations.
A book that reminds you of something specific in your life (a person, a place, a time).
There are so many of these. There's my hard cover 1st edition of the third book in Patricia McKillip's Riddle Master trilogy that the love of my life gave me and teased me by threatening to give away the ending (he'd read it first). There's my Pooh, that was given to me on my fourth birthday, and reminds me of my early childhood when I was innocent and happy. There are the books that I bought for myself with the salary from my first real job. There are the books I bought in the late lamented "Children's Book Shop" in Toronto, including a hard-cover Diana Wynne Jones (The Magicians of Caprona). My Moomin books that I bought in London when we went there on holiday in 1968. So many books...
A book you acquired in some interesting way.
This is also one of my most prized possessions: a copy of "Early Poems" by David Gascoyne, #1 of 100 signed copies, with a long inscription from the author, my Uncle David, congratulating me on having just graduated from university.
The book that’s been with you to the most places.
This would have to be one of the books I took with me to China. Probably my copy of The Lord of the Rings, which went to Toronto, came back here and then went to China and back.
The most recent addition to your shelves.
I just recently got the new Folio Edition of Possession
Your current read, your last read and the book you’ll read next.
I'm currently reading Patricia McKillip's The Bell on Sealey Head, which I'm enjoying quite a bit. Before that was William Gibson's Idoru, which was terrific. Up next - I have a couple of Y/A fantasies that are on two-week loan, so I'd better get at them. The priority is Margo Lanagan's Tender Morsels which I didn't remember ordering from the library but must have done, probably on the basis of a recommendation from one of you.
Feel free to play too, if you wish.
