FBI Agent Morgan Nash is on assignment in London when his case goes awry and he finds himself moments away from a bullet through the heart. But fate has other plans: Morgan gets knocked out pursuing a suspect... and wakes up in 1888. While cataloging ancient manuscripts at the British Museum, Ezra Glacenbie accidentally pulls Morgan out of the twenty-first century-an impromptu vacation that may become permanent for Morgan if they can't locate the spellbook Ezra used. Further hampering Morgan's quest to get home is the irresistible temptation to investigate history's most notorious serial killer: Jack the Ripper. But in repressive Victorian London, it's the unexpected romance blossoming between Morgan and Ezra that becomes the most dangerous complication of all.
