Overall I liked this collection of slipstream, interstitial short stories (certainly much more than The Jane Austen Book Club), though there were enough stories that fell flat and weren't particularly great that I'm giving this 3 stars rather than 4. The ones I did like are a great subtle blend of realism and the fantastic (somewhat similar to Kelly Link, though I enjoy Kelly Link's stories more).

My favorites were the titular story "Black Glass", "the Elizabeth Complex" (which approaches the person Elizabeth as a combination of Queen Elizabeth, Elizabeth Taylor, and Lizzie Borden), "the Brew" (Culloden and magical whiskey!), and the last two stories, which both deal with aliens/other worlds in a darkly funny way.
