The Vampire Lestat by Anne Rice

The Vampire Lestat (1985) is a novel by Anne Rice, and the second in her Vampire Chronicles, following Interview with the Vampire. Many events in the two books appear to contradict each other. These inconsistencies provide an example of the unreliable narrator, allowing the readers to decide which version of events they believe to be accurate.
Set in the late 18th century to the late 1980s, the story follows the 200-year-long life of the vampire Lestat de Lioncourt, and his rise from humble beginnings as an impoverished aristocrat in the countryside of France to the city of Paris to become a vain and arrogant vampire. After escaping his family and running off to Paris with his friend and confidante Nicolas de Lenfent (nicknamed Nicki by Lestat), Lestat is kidnapped and bitten by the rogue elder vampire Magnus, who orphans him on the night he is made. Tempe finds herself drawn deeper into a shocking and chilling investigation, set to challenge her entire view of humanity. ..
