Just finished Lords of the North (the 4th or 5th series of yours I have enjoyed). This may be my favorite because it has a compelling storyline, unusual insight into the complex relationships of ethnicity and religion, and research that lends credence to personalities – their hopes and actions. Because I read widely, it may take a month or two before I read Sword Song, but I have no doubt it will be true to the saga. Are you researching any other periods of pre-renaissance England? H Balikov
