The bus trip to Prague and the Banat unfolds differently than young Len could have ever imagined. Even though his grandmother always claimed he was a Drăculești and the last descendant of Vlad II, he never believed it himself. Until he is hunted by vampires in Prague – for Vlad and his family were considered bitter enemies of the bloodsuckers. Now they fear that Len is a harbinger: for the return of the Black Queen! They want to use him to access the ancient magical-alchemical records of the mysterious ruler. The only problem is that Len has not the faintest idea. About both the past and what is to come... And the past is significant, as the parallel, dramatic events surrounding Queen Barbara, Vlad Dracul, and rival vampire lords in Transylvania and Wallachia during the Middle Ages reveal.
