"Two years ago, rookie ATF agent Harper Rowe witnessed the death of her partner and mentor in a fiery explosion at the headquarters of a man they’d been investigating. The start of what became an obsession, tracking the man she held responsible for six months before finally apprehending him.
The first major score of her career, elevating her to a full-blown agent and providing some modicum of justice for her fallen friend. Accountability that lasted until the prison transport van was hijacked three weeks ago, releasing the murderer and seven other criminals back onto the streets, renewing the fixation Rowe experienced so long ago."
