I really, REALLY like Janice Kim's series. I know that they're introductory -- I'm still a relative newbie so her books work for me. Everything about the books works. The style of writing, the typeface/font, the drawings, the paper, the binding. Both physically and mentally, I find these publications much more entertaining than Kiseido's books. I don't mean to rag on Kiseido at all. It's just my personal preference that I like Good Move Press' physical publication more than most. I freely admit to being shallow -- the niceties of Janice Kims' books means that I flip through them the most to refresh my low level Go mentality.

Having said that, what else should I read and acquire? What's similar but will help me continue to grow as a Go player and enthusiast?

If you're just finished Kim's books (which are really the best introductory books I know), I'd suggest trying "Opening Theory Made Easy" to get a feeling how to play in the opening and Graded Go Problems For Beginners I and II, because almost everything in Go comes down to reading out a sequence and these books have a very good way of teaching it.
While progressing, you might want to take a look in this thread.

Nothing. But try Lessons in The Fundamentals of Go, which is also entertaining, though for different reasons.

Everything else is, indeed, quite dry and not very pretty.

Now that I think about it, the So You Want to Play Go series is kind of similar in some ways. Very light-hearted and approachable. While it's got less dense information than other books I've got, if you're looking for something you can pick up, read a chapter at random, and smile, it's worth a shot.
