They announced it back in October, but now the Amazon Kindle Singles page is live. Singles are expected to be about ten to thirty thousand words each, and it looks like they sell for a buck to three bucks each. Here are a few of the descriptions:

"The Dead Women of Juarez" by Robert Andrew Powell (31 pages, $1.99): It sounded like one of the great murder mysteries of our time: who was killing the women of Juarez? Journalist Robert Andrew Powell went to the Mexican border town to investigate, and separates fact from myth in a saga that eerily echoes the plot of Roberto Bolaño's epic novel "2666".

"Pakistan and the Mumbai Attacks" by Sebastian Rotella/ProPublica (38 pages, $.99): The U.S. investigation of the 2008 terrorist attack on Mumbai provides a detailed picture of the ties between Pakistan's intelligence service and a leading militant group. The latest reporting from ProPublica, the Pulitzer Prize-winning investigative newsroom.

"Homo Evolutis" by Juan Enriquez and Steve Gullans (58 pages, $2.99): Enriquez and Gullans—two eminent authors, researchers, and entrepreneurs—explore a world where humans increasingly shape their environment, their own selves and other species. They envision a future in which humankind becomes a new species — one which directly and deliberately controls its own evolution and that of many other species. One of the inaugural TEDBooks.
