Larsa is a dhampir half vampire, half human. In the gritty streets and haunted moors of gothic Ustalav, she's an agent for the royal spymaster, keeping the peace between the capital city's secret vampire population and its huddled human masses. Yet when a noblewoman's entire house is massacred by vampiric invaders, Larsa is drawn into a deadly game of cat and mouse that will reveal far more about her own heritage than she ever wanted to know.
