I’ve been really enjoying Mulholland Books’ site and blog, especially their “A Conversation with…” posts between two authors. The lastest one is Ed Brubaker and Duane Swierczynski. Matthew Bayan, an author and former gun expert, has some super-informative pieces up as well on the practicalities of guns and gun use in fiction.
Greg Rucka and Warren Ellis both have books out/coming out with Mulholland, and they’re an all-around great resource and place to check out online. The site has free online short stories to check out, as well as the weekly free Popcorn Fiction project (which of course I’ve submitted to).
As someone with an interest in reading and in writing, I really consider it an essential place to hit up online regularly. You should too.
