And actually there were two more as well, 'Mavis Belfrage' and 'McGrotty and Ludmilla', both by Alasdair Gray, but booklikes would only let me add ten.
My favorite: 'Stardust'. I've always been a sucker for a good fairy tale, and Neil Gaiman's a dab hand.
My least: 'Every Short Story'. I'm a big fan of Alasdair Gray, but I was somewhat disappointed to discover that I'd already read most of the best stories in previous collections, and the edition I read was rife with typos, missing and transposed lines, and other errors. Neither of these were any fault of the author's, but both curtailed my enjoyment.
