The Link: Pearl Vampire Chronicles

It's a very different world for vampires. They exist, in small numbers, entirely to control evil and protect the innocent. Their population is controlled by 5 strong, ancient vampires called The Elders. Only The Elders decide who becomes a vampire. Only The Elders know the process to create a vampire. Yet, vampire Matthew is deeply in love with human Sarah and desperately wants her with him forever. So, he convinces her, and himself, to embark on a journey together. A journey that will take them to the deepest, darkest corners of the vampire world. A journey to Mexico, Peru, Nigeria, Cairo, Paris, Haiti and more. Hoping that they will find enough vampires from the days before The Elders who can give them the clues to the change process. Hoping that the clues that they do find are the right ones, because, if they're not, Matthew could end up killing Sarah. Hoping that The Elders don't figure out what they are up to and capture, punish, or possibly even kill them. It's a race against time. Time that Matthew has too much of and Sarah doesn't have nearly enough.
