I bought this book because of the French Revolution background, but the story is so much more than that (in fact, Paris during the revolution barely features, but I was hooked anyway!): romance, a strong heroine, characters who earn the reader's trust and don't deserve it (and vice versa). The involvement of an Illuminati sect, the 'Fallen Angels' is well written, and adds to the darkness and danger of 1790s Paris, but seems rather superfluous to the conclusion. It was fun guessing the identity of Lucifer, the shadowy head of the Fallen Angels, and waiting to have my suspicions confirmed: the author neatly reminds the reader of certain character traits,to aid a mental game of 'Snap!' with the many 'dual personalities' in the book. The historical detail was slightly anachronistic, mainly concerning dance and dress (more Victorian than late Georgian or early Regency), but the descriptions of place and the chivalrous behaviour of the characters was certainly evocative of the time. This is my first taste of Bernard Cornwell - or Susannah Kells, in this case - and I shall certainly try and read the other two stories in this sequence!
