Fantasy & Science Fiction magazine assistant editor John Joseph Adams (AKA The Slush God) points this out:
David Louis Edelman, author of the kick-ass SF novel Infoquake [read my review], is giving away five signed copies
of the novel to the people who best accomplish one of five tasks, as
outlined on his blog. Some of the tasks sound like fun, so go give it a
shot. I'd happily enter, but I've already got a copy.
I'm tossing around the obscene limerick challenge. Go debase yourself for some free sci-fi right now.
