The Agency taught him how to fight monsters, not a war. How to protect his country, not those he loved. How to kill, not how to live. Now Craig Lockman faces a legion of vampires led by a self-proclaimed vampire king. Never before have these creatures amassed in such great numbers. Their goal is uncertain. Their reach unknown. And while Lockman's training can help in the battle against this dark legion, nothing can prepare him for the sacrifice he must make in order to defeat its king. This thrilling follow-up to Darker Things doesn't stop delivering wicked twists until the very last page. Don't wait a second longer. Grab your copy of Dark Legion now!
