Book excerpt: A gothic delight from Karen Maitland, author of the bestselling and much-loved Company of Liars, that will enchant readers of Kate Mosse's The Burning Chambers or fans of Deborah Harkness seeking a new, dark fix. 'An atmospheric and dark story' The Times Never trust your secrets to a Raven when you are not its true master... 1224. Langley Manor, Norfolk. Lord Sylvain has been practising alchemy in hiding for years and now only the Apothecary's niece can help him with final preparations to forge the Philosopher's Stone. Alchemy calls for symbols - and victims - and when a man in possession of an intricately carved raven's head arrives at the Manor in a clumsy attempt at blackmail, Sylvain has both symbol and victim within easy reach. But the White Canons in nearby Langley Abbey are concealing a crucial, missing ingredient... Regulus, a small boy with a large destiny. What readers are saying about The Raven's Head: 'An intriguing and exciting dark tale about power and intrigue in politics, but most of all about the power and fear of the main ingredient of the book - almighty alchemy!' 'Full of stories, witchcraft, alchemy, suspicion and suspense. Fantastic book' 'As well as being a suspenseful tale that keeps the reader on the edge of their seat, the book illustrates that the Middle Ages had a dark edge. The writing is beautiful, and the novel is crafted in a masterful way'
