Lowland Sea by Suzu Mckee Charnas is quite a grimly satisfying modern riff on Poe's mask of the red death. The Horrid Glory of its Wings by Elizabeth Bear is about a girl and a harpy and manages pathos without sentimentality. Sea Hearts by Margo Lanagan is delicious, rich poetic language and the story of the men who stole the selkies to be their wives, and the boys who loved their mams.
