I've been doing a daily blog for over nine years now. And I have a system. I like to plan posts in advance, and I start working on them well before the scheduled publishing date. But I made a boo-boo this month. I somehow managed to skip Friday, April 9 when I was making my blog schedule. And I didn't notice right away. So I was kind of scrambling to find something awesome and timely to plug into the schedule. And then something magical happened. I learned that April 9 is National Unicorn Day. And unicorns are having a moment in the children's publishing world.
