Piper Marmande believes Kendal has come to take over the company her family has built over generations. As Kendal prepares for the most important battle of her long life, Piper does her best to uncover every one of Kendal's secrets, making herself a distraction Kendal can't afford as she hunts Henri and Ora, the vampire who seduced him to a life of darkness.
