The war to save humanity has begun. And this time, love won't be enough to save them all. For years, the shadows have been gathering. The enemy has been building an army, manipulating the boundaries between life and death, and preparing for a final strike that will wipe humans off the supernatural map. Now, the storm breaks. To stop the Apocalypse, the Fallen Response Units must do the impossible: unite. Four celestial warriors who gave up Heaven for mortality. Four powerful mortals who taught them what it means to be human. And one really pissed off Nephilim who's not about to miss the fight. Azrael and Emma, Seraphina and Jake, Raz and Luna, Uriel and Sarah. And let's not forget Mathias... every leader, healer, and fighter from the past must stand shoulder-to-shoulder on the front lines. But the enemy has been waiting for them to gather. As the sky burns and the wards fall, the ultimate test of their fated bonds begins. They have fought for each other, bled for each other, and defied Heaven and Hell to be together. But in a war this massive, the sacrifices required to close the gates will cost them everything. Not everyone is walking away from this fight. The epic, devastating conclusion to The Fallen Response Unit is here. Grab your armor, hold your breath, and prepare for a final battle that will shatter your heart.
