I have email from HarperVoyager announcing an Open Door period for submissions. As with the Angry Robot one I wrote about last week, this means that you can send them manuscripts direct without having to go through an agent.
Full details should be available here, but it looks like the site is creaking under the excess level of traffic right now so I can’t be sure. The link should at least direct you to where you need to be.
What I do know is that you don’t have long. Angry Robot gave you the whole of NanoWriMo to write the book. HarperVoyager are looking for submissions in early November, so unless you have something ready this is probably not enough notice. But I know a lot of you do have something. Good luck!
