At the beginning of the month, I put out a call for people's opinions on the most neglected book of the year. Some people responded in the comments, some emailed me, and some responded on their own blogs. Here's what I've heard about so far -- feel free to add more in the comments to this post.
Kelly Shaw emailed with: "I'd say Peter Straub's In the Night Room. Straub's done some amazing stuff with his last 2 books and, though he gets some respect from the mainstream and publications like Locus, I think he deserves to be uttered in the same breath as the giants of the genre (Wolfe, Hand, Powers, etc .). So, though not obscure, I feel In The Night Room is under appreciated and is probably my favorite book published in '04."
Nick Mamatas suggested The Course of the Heart by M. John Harrison and Compositions for the Young and Old by Paul G. Tremblay.
Mentioned in the comments to the original post were Deadfolk by Charlie Williams, Prisoners of War by Steve Yarbrough, Double Vision by George Garrett, Axeman's Jazz by Tracy Daugherty, and D.B. by Elwood Reid.
Over at his blog, Jeff VanderMeer nominates two books he hasn't read.
And there's also a post and comments thread at Tingle Alley about the subject. (I was so glad to see TA advocating for The Plot Against America, because, as we all know, it's been neglected by evil elitists who give awards to books nobody's ever heard of. Definitely neglected. Definitely.)
