As a runaway in San Francisco, seventeen year old Xochi never expected to encounter the precocious preteen Pallas, or to fall into a position as the girl's governess. Soon, Xochi has taken up residence at the sprawling Victorian mansion belonging to Pallas' family, the glamorous rock band Lady Frieda. For the first time, she feels like she may have a place she belongs. Then one night Xochi and Pallas perform a riot-grrl ritual in good fun, accidentally summoning a pair of ancient creatures determined to exact vengeance for wrongs against Xochi. No one around her is safe - not her new family, nor the one she left behind.
