If it's JV fiction you want to sample, I'd say just go to a bookstore and pick up a title or two. It's hard to tell what's in print at any given moment, but both US and UK Amazon sites show quite a few titles, including both SF and fantasy. If the price of a new paperback seems too high, just about any fair-size used book outfit should have a decent sample of Jack's back list.
