A trip to London to see a friend's art exhibit should have been the perfect way to introduce Claudia to his interests, and she's excited to see how much the city has changed since the Londinium she knew in the fourth century. But Ezra doesn’t expect his feelings for her to shift into something more, and no one expected a demon to be accidentally summoned during the exhibit. Now that it's out and terrorizing London, it's up to the only two people in the city who know about the existence of supernaturals to stop it. After all, how can he tell her how he feels if he doesn't know if he'll live another day to do so?
