Eric - or King Halar, also known as the Demon King - has more than enough problems without the crown. But quitting the job of king isn't easy, either - unless you want to be beheaded. Most people regard that as an unsatisfactory way to quit. Even vampire lords tend to be cautious about guillotines. A king who loses his head has a real problem...or none at all. It's time to sort some of these problems out, settle a few more, and kill the rest. But at what cost? Knightfall is the fourth book of the Nightlord series. It picks up exactly where Orb (book three) ends, and carries on with an adventure of epic proportions!
