And really, the only preference that has been stated is "graphic novels, collections of short stories [...], and short novels" from prince_corwin, which means that the field is generally still pretty well open! Which since it's the 24th, I don't want it to be for too much longer. :p
The Orphan's Tales: In the Night Garden by Catherynne M. Valente - A lot of people sounded interested in this, with the main drawback being the book's length. Either it would be one *hefty* month of reading, or it would need to be spread out over two months.
The Wizard of Oz by L. Frank Baum - Suggested some time previously, seems to be one of those "no one hates it, no one's pounced on it" suggestions thus far.
The Best Short Stories of J. G. Ballard - Suggested somewhat recently, not much to comment on thus far. And as an added note after the last time, the one who suggested it was interested in it, but hasn't actually read it, so no guarantees for how well it'd work. :p
The Name of the Wind by Patrick Rothfuss - Suggested somewhat recently, I went ahead and included it just in case, but the consensus seemed to be leaning toward "oh gods, not another non-ended epic fantasy."
Wild Cards edited by G.R.R. Martin - Suggested by me, recently. There seemed to be some interest in this, but the main difficulty (and possibly an insurmountable one for this format) is the fact that it'd be damned hard to get hold of for those who don't already own it.
Unnamed Agatha Christie book - Suggested sometime previously, seemed to be at least some mild interest. Either we could do one of the collections of her short stories, which would work well with the format, or another book. (I myself lean toward The Murder of Roger Ackroyd which might be fun to read as a group.)
The League of Extraordinary Gentlemen volumes 1 and 2 - This was suggested by... me, I believe? Somewhat recently. It might be interesting, and the graphic novel format seems to work well for this type of thing, but a) it'd probably be something for future months if we do it, since we're just wrapping up V for Vendetta, and b) it'd involve buying two books, since the mini-series were 6 volumes each.
The Princess Bride by William Goldman, because dude. Suggested by me last month, didn't really get a chance to get discussed.
Hyperion by Dan Simmons, suggested elsewhere, which may be a bit on the long side overall, but sounds like it's broken up into six sections/novellas, which could themselves maybe be broken into half and read that way? I do not know, but if others have read it or have been enticed by it and could suggest yay or nay, please feel free!
And things I'm going to suggest now, along with anything suggested in comments that I'll edit in as well (including if I remember the other book I wanted to suggest then promptly forgot...)
Howl's Moving Castle by Diana Wynne Jones, because a) it's a good book, b) it's not overly long, and c) if we could drum up more participation, it'd be interesting to see how the commentary splits between those who have seen the movie but not read the book, people who have read the book before, people who have done both, and people who have done neither.
Mrs. Frisby and the Rats of N.I.M.H./The Secret of N.I.M.H. by Robert C. O'Brien, for many of the same reasons, although it's been longer since I've read this one (and it's probably more children's book than fantasy, technically).
Unnamed Discworld novel, since we ended up not doing Night Watch for May. (So sorta new suggestion, sorta old.)
Anyhow, that's what we have for now, so please, anyone, feel free to speak up? Anyone? (Is this thing on...?)
