Guess Which?

Oh dear, it's crept past midnight again (though I am trying to deceive the computer into thinking it's still Tuesday... we'll see if it works). And I'm very sleepy, so you'll have to prepare yourself for a book review tomorrow - to whet your appetite, I'll show you a photo of a bit of my bookshelf. The book I'll be reviewing is one of those in the picture... guess which. Not too tricky, perhaps, but means you get both text, photo and interactivity without me having to use my brain at all.
