The first draft of Remain in Light is nearly complete. I've been in touch with Vanilla Heart and we are discussing a timeline for publication. I can tell you that the ebook version will come first and the paperback a month or so later. Ebook sales of Conquering Venus trumped print, which is no surprise if you've been following the news that Amazon sold more ebooks than hardcover books in 2010 and reported just last month that ebook sales for the Kindle had even eclipsed paperbacks.
A couple of weeks ago, Kimberlee at Vanilla Heart sent over a round of cover concepts for Remain in Light and we've already picked one. I actually love it more than Venus, so I can't wait for everyone to see it very soon!
