The Glass River has been filmed with an international cast and is already on screen in Bulgaria. The novel begins with the arrival of the French student, Hélène Thibault, in the deserted Bulgarian village of Gradishte. She does her research work on the Bogomils for her diploma paper. At that time an art professor and his students are restoring the murals of the local church St. Nicolas. Two letters, N & D, are spotted on the frescoes of the church and Hélène becomes involved in resolving the mystery behind them. Have the letters anything to do with the dualistic Bogomil faith and especially with the short excerpt from an old manuscript, The Book of Enoch, that she is shown by the "local intellectual" Victor Markov? Hélène finds herself in a love triangle as well as in a series of astonishing events. A séance with the spirit of an Italian stonemason follows and eventually an old casket reveals the secret of the alleged Bogomil frescoes and letters.
