Please disregard my previous indication that I will be readying Lingua-U for release early next year. Upon immersing myself in an unfinished section of the book, I realize that it will take more time than I anticipated. I will post an update when the draft of the entire book is complete.
Meanwhile, check out The Kalendar website for the latest progress on the project. I will resume posting daily updates to The Kalendar on December 22.
