Back in fourth grade my class was assigned “The Lottery,” Shirley Jackson’s creepy story about a town full of stoners, but more recently there’s been a wave of interest in Jackson’s other work, like the awesomely gothic We Have Always Lived In The Castle. (Read it, if you haven’t.) But I have to confess ignorance about the Shirley Jackson Awards, which have been doled out annually since 2007 at a Boston-area nerd convention called Readercon. (I say nerd convention lovingly.) As a buildup to the July ceremony, a number of readers will tackle Jackson’s haunting work, as well as stories by some of this year’s nominees.
