To whoever reads this:
Good news! My first book is finally on track to get published. Haven't got any specific details from my publisher yet, but my book has been read through, and the company is offering ideas on it. I'm taking this as a good sign. Apparently my original draft was a bit long for a single volume, but that situation has been rectified. I don't have an estimate on why the book will come out yet, but I will post them as soon as I get them.
