Book excerpt: Short story. In the citadel, it's hard to tell who's your enemy and who's your friend - or it is for the Executioners. No wonder they need human guard dogs to protect them while they sleep. When Griselda's human is compromised, will one of her fellows take advantage of the situation, or will they hesitate long enough for her to find a solution? Who knew vampires had so many problems? Can be read as a standalone.
