Read it (way back in high school, I think).
Another nomination: Divided Kingdom by Rupert Thomson.
Another one who has read Bride of the Rat-God and Snouters.
Both well worth the read.
Probably the best book I can think of is Barry B. Longyear’s Saint Mary Blue, a novel inspired by his stay at an inpatient alcohol/drug addiction rehab facility. It’s a wonderfully affecting book, and a very good look at a modern group therapy based mental illness treatment facility.
A nice bit of fluff I’ve really enjoyed is Roger F. Young’s Eridahn. Also his The Vizier’s Second Daughter. (Dammit I loaned out my copy of that a few years back, and never got it back. sob) Both books are rather pedestrian time-travel adventures, without any really outstanding ideas, aside from a pair of romances that I cannot describe without sounding really skeevy. But, while reading the books, they work, and are enjoyable for what they are. Not deep works, but fun.
Haven’t read the middle one, but Tik-tok and The Marching Morons are among the most unforgettable things I’ve ever read.
Down to a Sunless Sea, by David Graham. It’s a horribly dated, racist and sexist post-apocalyptic thriller concerning the passengers of a trans-Atlantic airliner in the aftermath of a nuclear war, but there are a couple of passages that have stuck with me for twenty years - particularly the bit where the Russian plane needs to lighten the load.
Heh-heh-heh…I guess I still know how to pick 'em. 
Well, I’ve read several mentioned so far, including
Bear by Marion Engel
Divine Right’s Trip by Gurney Norman it sat on the shelf for years before I actually read it and found it was pretty good!
The Long Ships by Frans G Bengtsson
No One Thinks of Greenland by John Griesemer - I’ve been half-heartedly trying to remember the name of this one for a year or two now; thanks!
Silverlock by John Myers Myers
But how about The Green Child by Herbert Read? A child emerges from an underground cavern…
Or The Hope by James Lovegrove A huge liner that never docks for decades…
Or The Lost Traveller by Ruthven Todd. Although that’s getting a bit too obscure, I suspect! I used to read my dad’s old copy back in the 70s…
Mockingbird by Walter Tevis author of The Hustler, The Color of Money and The Man Who Fell to Earth. Just about the only SF I have read since I stopped reading SF in my early 20s. I only picked this up because I had read the two pool books and The Queens Gambit, a chess novel, and loved his style.
Suspects by movie critic David Thomson. A mysterious narrator fills in the life stories of about 100 characters from classic movies. What was Jake Gittes childhood like, who was Travis Bickle’s father, what happened to George Bailey after “It’s a Wonderful Life” ended. Were Noah Cross (Chinatown) and Nora Desmond (Sunset Boulevard) lovers in the 1920s, which famous plane crash killed Ilsa Lund(Casablanca)? The stories begin to intertwine, real people start to appear and the whole thing becomes a pleasure for fans of film noir.
Am I one of the few who’s read Norstrilia and The Best Of by Cordwainer Smith? For as highly influential as he was, I rarely see him mentioned. He’s still my favorite SF writer.
Oh, ha, I did a search after the fact and Voyager mentioned him August 11, in a thread I started, no less!
FYI, Norstrilia and five related stories have just been reissued in paperback by Baen as We the Underpeople (isbn 9781416555674)
Virgin Planet by Poul Anderson
It’s basically Planet of the Apes with women who’ve never met a man instead of apes who enslave humans. Oh, and it ends with our hero astronaut about to get it on with two female warriors.
It’s the greatest book ever.
I don’t really think for a minute that these will Stump the Dope™, but…
…anyone else read The Bear Comes Home by Rafi Zabor?
Space War Blues by Richard Lupoff?
I read Virgin Planet when it came out in the UK… when I was young I loved One Million Centuries by Lupoff, but when I saw Space War Blues years later it didn’t appeal, I’m afraid…
Yup - great book!
Ricardo Piglia’s ‘‘The Absent City.’’ (Originally La ciudad ausente.)
I read it in Spanish for a surrealist literature course, so I don’t know how great it is in English, but I found it absolutely hypnotic. It is the bizarre tale of a journalist trying to investigate a scandal – a machine (created by the husband of a ‘‘disappeared’’ woman) that is spitting out her unauthorized memories. It is chock full of literary and political symbolism and the beautiful, lush, stream-of-consciousness creativity I tend to adore. It’s also a heartbreaking look into the suffering and censure that Argentinians endured under the military dictatorship of the 70s and 80s. If you like Borges, you will like this novel.
The Tale of the Land of Green Ginger by Noel Langley. It’s much like The Phantom Tollbooth in that it can be enjoyed by kids and adults in different ways.
It’s out of print.
One of my very favorites, as good and anti-authoritarian as anything buy B. Traven.

ETA : A better link.

I’ve had Tik-Tok on my shelf for YEARS without reading it. I probably heard about it first here on the Dope. I’ll have to get it down finally and give it a spin.
I first read the Swedish decadent Hjalmar Soderberg in college. The priest-murdering Doktor Glas and the adulterers of The Serious Game provide fine novelistic entertainment.
Not only have I read it, I wrote a report for my high school biology class on it and got an A. 
The Last of the Really Great Whangdoodles by Julie (Andrews) Edwards
The Teddy Bear Habit
Two of my favorite books from childhood and I’ve never come across anyone who’s ever even heard of them. Please let me know if you have!
