As you can see from the photo (and the title of the post is a bit of a give away), this is a Japanese translation, and rather a handsome hardback. If you aren't sure if a book is Japanese or Chinese, in my experience the Japanese translations usually come with those distinctive paper strip covers (the yellow bit at the bottom) that only stretch to half or less of the book's size.
When I get translations like this I usually give them away when I do talks if I can find anyone in the audience who speaks the appropriate language, but as I've several to spare, I would be happy to provide one to any readers of this blog who would like them - I just ask that you pay the post & packing, which I reckon will be £4 in the UK, £5 for the EU - I'm asked not to send them outside the EU. If you would like a copy, just drop me an email at email@example.com with your address and I'll let you know how to pay for the postage.
Oh, and what was the book? It's Gravity.
