Lately, I haven't been scheduling posts, because I like to post them deliberately after I get home from work. But perhaps, for these Free Book Friday announcements, I should schedule them, since the sooner people know about the promotion, the more likely they will be able to take advantage of it.
Book 1 of Gatekeepers is available for free, right now.
