Spoilers:There is so much wrong with this book that I couldn't even begin suspending disbelief. Vampires are an ancient species of shapechanging parasites who coexisted with dinosaurs. Time travel can occur on a ghost train and that train can be hijacked by humans who just barely learned of its existence. Hudson Bay was created by a powerful nuclear weapon from the future transported to the distant past in order to annihilate the vampire species . . . bleh!
