Back in 2008, the Internet Review of Science Fiction (www.irosf.org) published an essay of mine, Space Opera Rules; But By Whom? I have not even thought about it for ages but to my surprise I have just received an email asking for permission to include that piece in a forthcoming anthology, Crimethink.
This collection is being put together in support of the work of Doctors Without Borders which I suggest is an excellent cause to support. I was quite happy to support the anthology. It should be available in the near future: crimethinksf.blogspot.com.
