Poets & Writers Magazine's September/October issue explores self-publishing, so today’s featured video clip is a book trailer for Wool, which was originally self-published in 2011 as a short story by independent writer Hugh Howey.

Wool, a science fiction series self-published last year by Hugh Howey and subsequently acquired by Random House UK for publication next January and optioned for film by director Ridley Scott and producer Steve Zaillian, is "the story of mankind clawing for survival, of mankind on the edge." The folks at Random House UK put together a pretty slick trailer; check it out.

In the latest episode of Self-Publishing Roundtable, Hugh Howey, the author known for his popular series Wool, which he independently published through Amazon's Kindle Direct Publishing, talks about his new website, authorearnings.com.
