The Heirs - The First of the Vampires, #1

Twenty-year-old Albert is the ambitious illegitimate son of an English duke. He 'inherits' a 'half-perfect' destiny in a closed and exclusive society in 1913. When he has to leave for Transylvania, Albert realizes he loves the aspiring Duchess Josepha - the Duchess' niece, living at the Duke's manor. At the abandoned medieval Transylvanian castle, Albert fights against a world of dark forces of the past and the vampires that surround the place, trying to make him one of their own.
He becomes a vampire most unexpectedly, and his immortality seems haunted by guilt. Tremendous forces call him to follow a more significant and challenging path in a vast world full of mysteries and blood, undermined by vampires led by the most tyrannical one. The wave of evil rises at the outbreak of the first world war, bringing unforeseen challenges, and Albert and his friends choose to fight to stop the vampires' plan.
What outcome will the big fight have? Will Albert be a victor or a martyr? Will he receive the reward for giving up fighting, or will he find another way?
