When you're mated to an immortal vampire, love is forever. Literally.

In another lifetime, six vampires lost their mates-and their mortality-to an unimaginable evil power. Despite the veil of death separating them, the strength of love draws them together across the ages. But now, if they can't reunite with the reincarnations of their lost soulmates soon, it may just mean the end of the world.

From London to Kuala Lumpur to the ancient ruins of Saqqara in Egypt, follow the nightwalkers who are all that stand between humanity and chaos as they try to gather together the prophesied Council of Thirteen. Six vampires. Six reincarnated mates. And... the mysterious Other. Without the Council, the world will fall to darkness and become a wasteland haunted by the undead. But the demon who covets dominion over humanity will stop at nothing to thwart the vampires on their quest.

In the eternal battle between Light and Darkness, love may be the greatest weapon... or the greatest weakness.
