The heart of Faerie is the heart of the world. While Oberon, immortal king of Faerie, lies under a terrible curse, the artistic spirit in the world is slipping away. The King's Raven would do anything to lift the spell, if only it hadn't also stripped him of his magic and flung him into an iron-bound past with a damaged memory. The only thing that can save them both is sealed inside a riddle wrapped in a puzzle that spans the centuries. Even with the help of an Elizabethan magus, a Victorian spinster, and a mad reporter, can mortal musician Ben Harper find Raven in time to solve the riddle, stop a witch, and restore the creative heart of the world? First, he'll have to find the key. King's Raven, second book of the Harper Errant series, sends Ben on a journey from the castles and taverns of Old England to the British Museum on Christmas Eve, and from the Crystal Palace of Victorian London to wintry Dartmoor to a magickal conclusion.
