Yay! Even with all the delays, you win our race. :)
But aren't you going to put out a few books at once?
Hoping to get at least three out this year, maybe four if I'm lucky. The "race" was for the paperback of my Let's Play Math, which has turned into a second edition with two new chapters and lots of extras. Planning for summer, or for back-to-school at the latest, barring unforeseen trouble.
What a beautiful suite of books people will have to help them change their perspective on math!
