Justin Somper's high-octane Vampirates sequence, fusing pirate adventure and vampire myth, is published in 34 countries and 24 languages. The six book sequence concludes in June 2011 with Immortal War. Justin has one of the most active and dedicated fanbases of any author, with 6000 regular Vampirates VIPs. Fans have nicknamed themselves "the Nocturnals" in homage to a key Vampirate ship, The Nocturne and have set up several fan websites. They have also launched an online petition for the books to be turned into a movie.
