The Sword and Laser discussion

Can anyone recommend any Facebook author/reader groups like Grimdark Fiction Readers & Writers? I'm basically looking for other forums online where I can promote my book Devil's Night Dawning... I've found GFRW quite fruitful and I thought there must be others around?

Thanks for reading - any help would be appreciated :)

Look here.
