Eunoia by Christian Bok, the "upgraded" edition from 2009 (2010 2nd printing). 115-page paperback from Coach House Books (Canada). Used copy in very good condition, just rubbing/scuffs to the cover, otherwise clean and tight.
It has one of my favorite dedications: "for the new / ennui in you"
'Eunoia is a novel that will drive everybody sane.'--Samuel Delany
'A marvellous, musical texture of rhymes and echoes.'--Harry Mathews
