Break Down - Sara Paretsky

When a group of Chicago tweens holds a ritual in an abandoned cemetery, they stumble on an actual corpse — stabbed through the heart in a vampire-style slaying. V.I. Warshawski arrives on the scene to escort the girls home–but protecting them places her at the tangled center of the investigation. And the girls include daughters of some of Chicago’s most powerful families: the grandfather of one, Chaim Salanter, is among the world’s wealthiest men; the mother of another, Sophy Durango, is running for the United States Senate. For V.I., the questions multiply faster than the answers. Is the killing linked to a hostile media campaign against Durango — or to Salanter’s childhood in Nazi-occupied Lithuania? As V.I. struggles to find an answer, she finds herself fighting enemies who are no less terrifying for being all too human.
