Ellen Ullman's Close to the Machine, a memoir of her time as a software engineer during the early years of the internet revolution, became a cult classic and established her as a writer of considerable talent; with her second book, The Bug, she became an acclaimed and vital novelist; By Blood is her third. All three titles are published in the UK by Pushkin Press. Her essays and opinion pieces have been widely published in venues such as Harper's, The New York Times, Salon, and Wired.
