Dark Legion — Rob Cornell

Craig Lockman Returns... 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.
