I've already had one suggestion, for Wizard of Oz, which might be interesting. (I've only read the book one time, and that a long time ago, sorta like I, Robot, but I remember liking it more.)
There was also Frankenstein which still is hovering in the background, and I also thought Dracula in the same, ahem, vein might be interesting to read, although I'm not sure we'd want to do a second Victorian novel in a row.
Finally, I'd also like to tentatively suggest Watership Down to read at some point, because it's awesome, although it might be too long really for this format.
Anyhow, please make with any discussions/suggestions!
