Core of Steel

Staff Sergeant Bea “Mic” Michaels is the leader of Steel Corps, an elite group of the finest men in the American armed forces. Commissioned by the US government to do what other units cannot, existing both above and outside the law.
A new recruit, Corporal Chris Jordon, has just been delivered, but before he can call himself Steel, he must pass every physical and mental test Mic throws at him. Orders for a mission have come down, and Mic must train Jordon faster than ever.
Their team is thrown into a desperate mission to rescue an undercover operative in the heart of Colombia. Forced to take down the head of the Fernando cartel and the mysterious Frenchie, their mission is complicated when Mic and Jordon are lost to their team.
Digging deep within herself, Mic will need every ounce of her strength to save both her team and herself.
