Hi!
I’ve been learning a lot through the free resources (thanks!), and am really interested in acquiring the book. Was trying to buy it right now, actually, but then I noticed there’s no Kindle/eBook option. After searching around on the forums, I saw some mentions of an eBook possibly being made, any news on that?
I live in Brazil and I’m pretty sure I can get it shipped here, but not only would it take around a month, it would also cost around double the price due to import taxes (at least, that’s what Amazon tells me). Given the state of our money compared to the dollar, that’s a bit prohibitive in my current financial situation. 
Hope there’s a way to get access to the book in digital format!
