Summary from Goodreads:
A modern-day thriller about Rory, an American high-school student who enrolls at a London boarding school for her junior year. Soon after her arrival, a series of murders begins to take place across the city—on the exact dates and in the exact style of Jack the Ripper. Rory’s ties to the killer bring her in contact with a secret paranormal branch of the British police, as they attempt to stop the mysterious killer.I think that perhaps I've just died and gone to heaven because this novel looks incredible! It's filled with everything I crave in a novel--mystery, far off places, a paranormal branch of police and a killer. I'm sold! I've only read one of Ms. Johnson's other novel and really enjoyed it. I can't wait for this one!
