The Black Tide

Though Winter Halo - the pharmaceutical company behind the evil experimentation on both children and adults - has been destroyed, the danger is far from over. Not only do seven children remain unaccounted for, but some of the vampires are now able to walk in light. The key to stopping the unthinkable lies in finding Ciara Dream, the last member of the trio behind the plot to give full light immunity to both the vampires and the Others.
But Ciara, like Tiger herself, is a shapeshifter, able to take on any human form she desires. To find her, Tiger will need to use every skill in her formidable arsenal, and even that might not be enough to save the city and the people she has started to care about. Because the vampires are coming, and this time, the lights won't stop them.
