When a high security prison fails, a down-on-his luck cop and the governor’s daughter must team up if they’re going to escape in this "jaw-dropping, authentic, and absolutely gripping" (Harlan Coben, #1 New York Times bestselling author) bestselling thriller from Adam Plantinga, whose first nonfiction book Lee Child praised as “truly excellent.”

Argento must help a small band of staff and civilians, including Julie and her two state trooper handlers, make their way from the bottom floor to the roof to safety. 

All that stands in their way are six floors of the most dangerous convicts in Missouri
