I am shamelessly choosing these books in order of length, starting with the shortest. I am sure I will regret this in December, but it serves my purpose now, so... I'm in.
I love Nick Bantock, best known for his Griffin and Sabine trilogy/series (remember those?) His art is mesmerizing and his story telling is so magical.
I have read most of his books and loved them all, but I particularly enjoyed a non-fiction work of his called Urgent: Second Class. In it, he discusses how he makes his art in great detail -- it's so inspirational.
I know very little about this one, other than... it's a fictional story, interlaced with Bantock's beautiful illustrations and [flipping through it now] ooh! Looks like some letters, too! Yay!
