Every issue of Lightspeed offers science fiction, fantasy and author interviews. In it you can read all types of speculative fiction from near-future, sociological, soft sf, to far-future, star-spanning SF. And, all types of fantasy--high fantasy, contemporary urban tales, surrealism, magical realism, science fantasy, folktales...and anything and everything in between. Lightspeed consistently delivers brilliant stories by some of my favorite authors and also introduces me to emerging talents.
I also love the author interviews: getting a behind the scenes peek at what motivated the author, how the story developed is always fascinating. And to top it off Kindle subscribers get exclusive content not available online: I like that lots!
The editor, John Joseph Adams, has published a bunch of brilliant anthologies including Wastelands, and Brave New Worlds. I'm very happy with my Kindle subscription because each issue lets me delve into wondrous worlds, mind-opening ideas, and character driven stories. Highly recommended.
