New adventures and new characters from the master of young adult fantasy, Yevgeny Gagloev! In the very heart of Prague, beneath an ancient, mystery-shrouded house of Faust, a gloomy dungeon is suddenly discovered, filled with strange inhabitants and mysterious inscriptions on the walls. Who will help decipher them? Naturally, Igor, Maxim, and Kira Knyazev. Curious, quick-witted, and upbeat, the siblings are always ready for an adventure—whether it's finding a hidden cache, solving a puzzle, or decoding a message in an unknown language. And if one adventure leads to another, full of unknown dangers, the Knyazevs will only be happy. The more secrets and surprises, the more fun!
