My latest novel, CODA, has just been published about the mysterious death of Tchaikovsky. It is anchored on facts and letters. Although it is alternate history, i.e., fiction, it gives insight into his life and the creation of his masterworks. Check out www.CodaTheNovel.com and watch the trailer.
I am a pianist and have studied the lift of this great composer extensively. I've traveled to Russia recently to get insight into the how his works and life are seen today.
