PLEASE don't kill Evi off! I understand that describing every day of her life makes this potentially endless,
and on top of it you're attempting the biography of the 20th Century, so yes it's a mammoth task. But I've read published diaries, collected letters and such that had big gaps in them. I'm sure you could find a way to skip a couple of years if you need to. Something like (and forgive my lame imitation of Evi's voice):

I had suspected the old hotel wasn't safe, but dear Vaslav was a nervous wreck prior to his premier performance of The Rite of Spring the next day---and especially with how that beastly Dighaliev has been treating him since he had finally put his foot down regarding their liason---and begged me to stay with him that night. When the fire tore through the Hotel Josephine at 2 a.m. we barely escaped with our lives. A small consequence compared to the fate that befell so many of the establishment's guests, but nonetheless quite vexing to me, was that I had brought this year's diary, and last years as well, in hopes of finding a passage that I wanted to read to my dancer friend. And those were lost. The record of over a year of my life swept into the skies over Paris by that unholy conflagration. Allow me to recap...

Anyway, I'm gonna find me a chunk of time and read this latest part ASAP.
I love this series, and Evi, her friends and all her cool adventures...
