New Voices competition, or even if you're simply working on writing a romance and want some great tips, Mills and Boon have a free e-book available now called Secrets Uncovered. It's full of tips from the editors and several Mills and Boon authors. There's even a bit from Fiona Harper and me - condensed from our workshop we did in New York in June.
You can download it on the Mills and Boon site - just scroll to the bottom of this page and look at the right sidebar. It's in epub format, by the way.
