As mailing lists go, it's going to be pretty darn low key, meaning you'll get very, very occasional newsletters from me. And since I like to think you might get something out of it, when you sign up, one of the confirmation emails you receive will have links to download a novelette first published in Interzone magazine last year. You have the choice of downloading in either Kindle/mobi or ePub format.
All you need to do is click on the link at the top of the sidebar on the right, and that'll take you to a form where you can enter your email address.
EDIT: Some people are having trouble seeing the sidebar. If you can't see it, click on "contact/mailing list" in the menu bar (hopefully you can see that) and that'll take you to another version of the signup page. Alternatively, click here.
Note that, outside of buying the relevant issue of Interzone (which I also highly recommend, because it's Britain's oldest and best science fiction magazine and helped launch the careers of dozens of well-known writers), this is the only way you're going to be able to get hold of that story. For now, anyway.
Once you've entered your email address, you should get a confirmation containing links to the ebook emailed to you. I'm new to this, so any problems, let me know!
