A Romance of Two Worlds [EPUB ebook] 

This narrative unfolds in London, where a young improvisational musician battles debilitating depression. Traditional medicine fails, leading her to a mystical encounter with Raffello Cellini, an Italian painter with a secret. His elixir induces vivid visions, easing her neurasthenia. Directed to Paris, she meets Heliobas, an enigmatic Chaldean Christian with extraordinary abilities. Alongside Zara, a sculptor, and Prince Ivan, the tale weaves a tapestry of mystical friendships, unrequited love, and the pursuit of inner healing against a backdrop of artistic and spiritual exploration.
