I loved A Confederacy of Dunces and have no recollection at all of the ending.
Do research books count? I just read five in rapid succession in the last two weeks, somewhat overlapping:
Breaking The Rules: The Wooster Group by David Savran
Nine Years Among The Indians, 1870-1879 by Herman Lehmann
Bury My Heart at Wounded Knee by Dee Brown
On the Art of Noh Drama by Zeami, translated by J. Thomas Rimer and Yamazaki Masakazu
Occasional Work and Seven Walks from The Office for Soft Architecture by Lisa Robertson
Nine Years Among The Indians was actually a pretty fun read, if disturbing, and the Lisa Robertson book is pretty amazing.
I want to get back to something fun, or perhaps a classic, but in between all the research reading and my work, all I have the brainpower for are comic books. I've had Tearing Down The Wall of Sound out from the library for over a year now, and am hoping to get to Sam Lipsyte's The Ask.
