This is probably my favorite series I've ever read, and you my favorite author. You're absolutely amazing! Your works are stunning and emotional and extremely well-written, even with the occasional grammatical errors, which, considering that English isn't even your first language, are practically negligible.
This series in particular was especially superb. I absolutely adore the way you write the relationship between the Master and the Doctor. And I also love that you're not afraid to kill off the Doctor. (It's fanfiction; it doesn't have to be canon compliant!) This was perfect in every way and I thoroughly enjoyed reading it. Keep up the great work!
