City of the Sun. Book 4. Heart of the Darkness

Before you is the fourth and final book of the series City of the Sun. A series that combines detective fiction, family saga, and thriller. Just seven months ago, students from Moscow Polytech had no idea that they would travel... to India, then to Sri Lanka, and then cross the ocean to Peru. The desperate journeys of the heroes will end in the rainforests of Latin America. Maxim and his friends follow in the footsteps of the Peruvian planter Carlos del Campo and the Russian manufacturer Alexei Zatrapezny, who founded the legendary City of the Sun deep in the Amazon. It is here that the greatest mystery of the Chavin civilization will be revealed, protected for centuries by the chosen ones from around the world.
