Return of the Dragon by Alex J. Webster

Return of the Dragon tells the terrifying tale of a mysterious vampire in 1950s Romania on an arduous trek to his castle in Transylvania. After learning scattered details of the vampires journey through a string of letters and reports about terrifying incidents through the years, readers meet Gheorghe in the town of Oradea. In post-WWII Romania, the Soviet-backed secret police are using harsh tactics to impose communist ideals, and regular people like Gheorghe are forced to go along with their comrades to survive. After a string of child abductions occur, Gheorghes scheming superior suspects that a group called the Order of the Dragon is trying to undermine the Peoples Republic, and he seizes the opportunity to ingratiate himself to his Russian overlords by nipping them in the bud. As Gheorghe investigates the mysterious disappearances further, hes drawn deeper and deeper into the chilling world of the Master. With his gypsy blood allowing the powerful vampire to pressure him from one side and his arrogant boss pushing him to help further his agenda from the other, Gheorghe feels as if hes stuck in a vise thats closing in around him—and theres no escape!
