Rather than be a pest and e-mail Mary asking when, exactly, her Hugo nominated story would be available to read for free, I decided to wait like a good boy.
Per this post at Mary Robinette Kowal's blog, "Evil Robot Monkey" is freely available to read.
Except, because Mary is all creative and stuff, we've got three options.
Read some plain text on the blog post itself.
Read a PDF chapbook beautifully designed by Mary herself.
Or, listen to Mary read the story (link on her blog).
Awesomely awesome. I'm going to read it tonight. And then probably listen to it.
