Compare Prophecy (Giordano Bruno Series #2)

It is the year of the Great Conjunction, the year the powerful planets of Saturn and Jupiter align to herald the end of one age and the dawn of another, and the streets of London are abuzz with predictions of Queen Elizabeth’s death. When one of the queen’s ladies is found dead amidst rumors of black magic, Elizabeth calls upon Giordano Bruno to solve the crimes, along with the help of her personal astrologer, John Dee. But while Dee turns to a mysterious medium claiming knowledge of the murders, Bruno fears that something far more sinister is at work.
