Followng a recommendation some time back by
the_alchemist, I have just read The Three Incestuous Sisters" by Audrey Niffenegger.
It is a very, very curious book, but in its own way quite brilliant. As she herself says, it's meant to be a novel told in pictures - the text exists purely to filter out erroneous readings, and is pared to the bone until it resembles one of those Japanese fables where absolutely every word counts.
The pictures, meanwhile, are simple but very effective - "shapely in their nakedness", to steal a phrase from Tolkien. The most obvious influence is Edward Gorey, which is perhaps inevitable in aquatint, but they also share a lot with David Hockney's line illustrations for (I think) Grimm's Fairy Tales. They are at their best when at their simplest - the sketching of expression, reinforced where necessary by a few words of text, is very effective.
One picture is supremely effective - about a third of the way through the book is a picture decribed only as "In Bettine's bedroom", which is the most gorgeous representation of all that love-making is meant to be.
The one thing the book lacks is plot. It is so pared back in its story development that it makes Magnus Mills look like Charles Dickens.
I wouldn't say the book is necessarily worth lashing out 17 quid on - my copy came courtesy of the awesomely good central library in Norwich - but it is certainly worth having a look at if you get chance.
