In 1641, the country of England stands divided. London has become a wasps' nest of spies, and under the eyes of the Roundheads those who practice magic are routinely sent to hang.
Living in exile in the Surrey countryside is the Master Astrologer and learned magician William Lilly. Since rumours of occult practice lost him the favour of Parliament, he has not returned to the city. But his talents are well-known, and soon he is called up to London once more, to read the fate of His Majesty the King.
What he sees in the stars will change the course of history.
Only Lilly and a circle of learned astrologers - Cunning Folk - know that London is destined to suffer plague and fire before the decade is through, and must summon angel and demon to sway the political powers from the war the country is heading toward. In doing so, Lilly will influence far greater destinies than his own and encounter great danger. But there will be worse to come . . .
An epic telling of the role of magic in the English Civil War, The Magick of Master Lilly is the story of the most influential astrologer in English history.
