The SF Site: The Homepage for Science Fiction and Fantasy is the brainchild of John O'Neill, Wayne McLaurin and Rodger Turner. The SF Site publishes articles, reviews, news, and materials related to science fiction and fantasy, in print and media, on the Web and off. They also have interviews with writers and artists, and links to bookstores and other SF-related sites.
I've known Rodger since I was fourteen, and used to work with him and Pat Caven at the House of Speculative Fiction in Ottawa. I have just written my first review for the SF Site (The Sparrow and Children of God by Mary Doria Russell), which should be up soon, and I will link to it from here when that happens. I hope that I will be writing more reviews for them, and am working on a number at the moment.
