Mariano is still working on the next 7 volumes....about 1000 pages per book according to historian Nicolas Anda de Sanchez. Mariano had surgery a few weeks ago and is aiming for a book release around May or June of this year. My cousin is good friends with Nicolas, and Nicolas had spoken with Mariano.
I'll keep you posted as we are all very anxious about the new books.
