The Devil's Looking-Glass soa-3

Will Swyfte, Elizabethan England's answer to James Bond, returns in his third swashbuckling supernatural  Swords of Albion  adventure.
1593: The dreaded alchemist, black magician and spy Dr John Dee is missing.  Terror sweeps through the court of Queen Elizabeth, for in Dee's possession is an obsidian mirror, a mysterious object of great power which legend says could set the world afire. And so the call goes out to celebrated swordsman, adventurer and rake Will Swyfte -- find Dee and his feared looking-glass and return them to London before disaster strikes. But when Will discovers the mirror may help him solve the mystery that has haunted him for years -- the fate of his lost love, Jenny -- the stakes become acutely personal.
With a frozen London under siege by supernatural powers, the sands of time are running out. Will is left with no choice but to pursue the alchemist to the devil-haunted lands of the New World -- in the very shadow of the terrifying fortress home of England's hidden enemy, the Unseelie Court. Surrounded by an army of these unearthly fiends, with only his sword and a few brave friends at his back, the realm's greatest spy must be prepared to make the ultimate sacrifice -- or see all he loves destroyed.
Review A plot that races like a flaming whippet on crack...darkly ingenious...hugely entertaining...streets ahead of most works in this genre SFSITE Smart, fun, at times surprisingly moving, and occasionally downright shocking...impossible to put down REALMS OF FANTASY
