Everything has a beginning. Even some of the most sickening creatures alive have a beginning to their story. But yet, what is a beginning worth of there is no point? No purpose? Even some of the most vile monsters have a purpose.

Be sure to check out the first book (The Protector Trials) in case you haven't seen it. Two years have passed since the fall of Citadel and the end of The Protector Trials. Project Delta, Zero, and Annabell have finally begun to taste the surface life they fought so hard to protect. But peace never lasts. When a mysterious letter arrives, hinting that more Alpha Series remain trapped deep within the ruins of Citadel, the bond forged in blood and fire is tested once more. Drawn back into the sunken city, the trio discovers that the shadows of Citadel still whisper-and one whisper leads them all. As Delta, Zero, and Annabell descend into hostile new terrains, they confront enemies deadlier than ever, both familiar and unknown. Citadel is not as lifeless as they believed. And somewhere within its depths lies "The Crown," a secret that could unravel everything they thought they knew about the Alpha Series. With survival at stake and The Crown tightening its grip, Delta must push beyond his limits and redefine the bond that ties him to his family. If they succeed, they may bring the last of the Alpha Series back to the surface, offering them a chance at freedom. If they fail, Citadel will claim not only its forgotten children... but its greatest creation.

Citadel. A modern city lying at the bottom of the Atlantic Ocean, untouched by the surface. On one fateful New Year's Eve, chaos erupted as drug-fueled citizens turned violent, throwing the city into a full-scale war. Citadel's elite defense force - The Alpha Series - was deployed into the heart of the city. Only a few would make it out alive. Now in this heavily "BioShock" inspired Novel, after three months of silence, two of the Alpha Series' finest - Project Delta and Project Zero - awaken to find their beloved city in ruins. Together, they set out with the few remaining protectors to reach the city's last hope: a hidden lifeboat to the surface. But as they journey deeper into the wreckage, they uncover a darker truth... Citadel isn't just dying. It's hiding something.
