Vampirates [EPUB ebook] 
Empire of the Night

Everything is about to change… Sidorio and Lola return from their icy honeymoon with plans to accelerate their reign of terror. Grace and Connor each receive an invitation to spend time with their true father and self-styled wicked stepmother. The twins find themselves drawn into an exotic new realm, filled with temptations as it is fraught with danger. With the Vampirate Captain still ailing, his guru Mosh Zu enlists the help of Darcy Flotsam and Lorcan Furey in an unprecedented mission… to forge an alliance with the Pirate Federation against the renegade Vampirates. As the first shots are fired in the war to control the oceans, key lives are lost and longstanding allegiances called into question.
