It's a long time since I read a vampire novel, although I remember being hooked on Bram Stoker's Dracula many moons ago. This vampire novel, though, is nothing like the Stoker one. This is a gripping story with a historical base. Martin and Sean are the two main characters and the reader first meets them when they are keeping watch from Hadrian's wall in case the black hordes invade. The black hordes, of course, are a vampire army led by the boy king, who is part of the Royal Stuart dynasty. This is a strange mix of history, myth and vampire lore, but it is gripping and keeps the reader reading right until the end. I must admit I was a bit disppointed at the end, not because the story wasn't good, but because it ended on a cliff hanger and I felt there should have been more. Somehow or other the story didn't seem to be finished. But this is a trilogy, so I suppose, if I want to know what happens next I'll have to keep following.
