Stoker and Holmes never meant to get into the family business. But when you’re the half-sister of Bram or the niece of Sherlock, vampire hunting and mystery solving are in your blood. And when two young society girls go missing—one dead, one disappeared—there’s no one more qualified to investigate. Now fierce Evaline and logical Mina must resolve their rivalry, navigate the advances of not just 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 16-year-old young women are in danger, they’ll become the next victims.
