Evaline Stoker and Mina Holmes never meant to get into the family business. But when you're the sister of Bram and the niece of Sherlock, vampire hunting and mystery solving are in your blood, so to speak. And when two young society girls disappear-one dead, one missing-there's no one more qualified to investigate. Now fierce Evaline and logical Mina must resolve their rivalry, navigate the advances of not one but three mysterious gentlemen, and solve a murder with only one clue: a strange Egyptian scarab. The pressure is on, and the stakes are high-if Stoker and Holmes don't figure out why London's finest sixteen-year-old women are in danger, they'll become the next victims.
