"You ain't gonna like what I have to tell you, but I'm gonna tell you anyway. See, my name is Karen Memery, like memory only spelt with an e, and I'm one of the girls what works in the Hôtel Mon Cherie on Amity Street. Hôtel has a little hat over the o like that. It's French, so Beatrice tells me." Set in the late 19th century—when the city we now call Seattle Underground was the whole town (and still on the surface), when airships plied the trade routes, would-be gold miners were heading to the gold fields of Alaska, and steam-powered mechanicals stalked the waterfront, Karen is a young woman on her own, is making the best of her orphaned state by working in Madame Damnable's high-quality bordello. Through Karen's eyes we get to know the other girls in the house—a resourceful group—and the poor and the powerful of the town. Trouble erupts one night when a badly injured girl arrives at their door, begging sanctuary, followed by the man who holds her indenture, and who has a machine that can take over anyone's mind and control their actions. And as if that wasn't bad enough, the next night brings a body dumped in their rubbish heap—a streetwalker who has been brutally murdered. Bear brings alive this Jack-the-Ripper yarn of the old west with a light touch in Karen's own memorable voice, and a mesmerizing evocation of classic steam-powered science.

Readers met the irrepressible Karen Memory in Elizabeth Bear’s 2015 novel Karen Memory, and fell in love with her steampunk Victorian Pacific Northwest city, and her down-to-earth story-telling voice. Now Karen is back with Stone Mad, a new story about spiritualists, magicians, con-men, and an angry lost tommy-knocker—a magical creature who generally lives in the deep gold mines of Alaska, but has been kidnapped and brought to Rapid City. Karen and Priya are out for a night on the town, celebrating the purchase of their own little ranch and Karen’s retirement from the Hotel Ma Cherie, when they meet the Arcadia Sisters, spiritualists who unexpectedly stir up the tommy-knocker in the basement. The ensuing show could bring down the house, if Karen didn’t rush in to rescue everyone she can.
