Ideally a book would have no order to it, and the reader would have to discover his own.
-- Mark Twain
As several of my friends and associates have heard, I have been known to read portions of books in an order other than that suggested by their page numbering. I started doing this when I was reading "The English Patient" and "In the Skin of a Lion" by Michael Ondaatje while travelling. Those books in particular were structured in a way that lent itself to a fractured reading. I read through some sections two and three times as I continually forayed through the work, until I no longer encountered unfamiliar material, or until I decided to go back through the book from beginning to end, skipping or skimming through the sections I had visited before.
The idea is not dissimilar to the work of William Burroughs, in which he intentionally distorted the narrative using his "cut up" technique. However, where Burroughs edited the randomness, the method I ocassionally use is truly random, and is a nice way to nibble at a work before eventually consuming it outright.
I hadn't made use of this technique for a while, having fallen back into the usual front to back method of reading. It was quite by accident that I engaged in a variation on the theme over the holidays. I purchased a handful of Ken Macleod novels at a bookstore in Los Angeles, and read through them over the course of a few weeks. It was only after reading through "Dark Light" and "Engine City" that I discovered that what I thought was a two part series was actually a trilogy, and that I had inadvertantly saved the first book for last.
As luck would have it, the story arc was structured in a way that lent itself to this treatment. The second and third books are set in an increasingly distant future. The first book is set in the near future. There is a bit more of a gap between the first and second books than between the second and third, so the overall narrative ended up reading like a two-part arc with a very nice prequel.
Anyway, I won't go into too much depth, as I don't want to spoil anything. Suffice to say that the universe in which these three books take place is vibrant, detailed and richly peopled. Of the three, the first ("Cosmonaut Keep") is probably my favorite, as the main character is a project manager working in software development... :)
