The Undying "screams for a sequel" (Publishers Weekly) - and Ethan Reid delivers in this riveting follow-up to "a thriller that brings a genuinely fresh take to a monstrous mythology" (Andrew Pyper, number-one best-selling author of The Demonologist).

The fate of the world is in his hands.

The Undying: Shades finds American student Jeanie and her young charge, Ren, 15 years after the EMP that wiped out Paris and sent them on the run from the undying. Walking the highways and hiding out in abandoned buildings across France, they eventually find their way to Spain and the walled city of Ronda, where a few dozen survivors have gathered - safe enough from the hunting undying but facing a new threat on the scorched planet: starvation.

With their main resource - humans - bordering on extinction, the undying have weakened, retreating to their hives and slowly withering away. But not for long. A dark presence arrives, casting its shadow across Spain, reawakening the hives and creating a new breed of monster. Driven by some alien intelligence, these Shades not only reanimate the undying but can possess the living, turning survivors against one another.

When Ronda comes under attack, Ren saves the day. As the youngest human left on Earth, he has been blessed with a special gift that makes him a perfect killing machine - and the last hope of humanity. Forced to leave the safety of the barricades, he takes to the highways with a company of Spaniards who intend to eradicate the undying from Europe hive by hive, using Ren as their secret weapon. But as they approach Sevilla to face the most powerful Shade yet, Ren learns some in his company aren't all they appear to be....
