In this second book of the Lucid Dreaming Experiments series, our time-traveling hero, musician Max Burton, takes off for another venture. After some cajoling he is convinced to visit the court of Frederick the Great and possibly save Frederick from his abusive father and save the life of Frederick’s youthful lover. Max also sees this visit as an opportunity to solve one of the greatest mysteries of music history: who wrote the theme for JS Bach’s A Musical Offering. Max finds the court peopled with characters from his other time-travel adventures, experiences love, friendship, and danger.
