Lieutenant Callum "Wraith" Knox leads a covert spec-ops unit with precision and detachment. Operating under the belief that emotion is fatal, he has buried his feelings to become a ghost on the battlefield. His reputation for being silent and deadly is unmatched until Sergeant Arden Locke joins his team. Blisteringly skilled and fearlessly idealistic, Locke challenges Knox's cold demeanor from the start. After a classified mission collapses, she is reassigned to Knox's unit, where her unwillingness to blindly follow orders sets them at odds. Locke's presence rattles Knox, stirring emotions he thought long dead.
During their first mission together, their clashing personalities create tension, but their combined skills prove formidable. However, when a high-stakes operation goes awry, Knox and Locke find themselves stranded in hostile territory. Cut off from support and surrounded by enemies, they must depend on each other for survival. This forced partnership evolves as tactical necessity gives way to unexpected trust and attraction. The more they rely on each other, the more Knox feels the walls around his heart cracking.
Task Force 141 has faced impossible targets before - but not like Makarov.
He's always ahead, always hidden and every move they make only seems to bring them closer to failure. That's where Cipher comes in. An SIS operative trained to disappear, to get close and to do the kind of work that soldiers aren't built for.
Now embedded with 141, Evelyn has one job: help them outsmart the man who's always two steps ahead. But as the mission pulls her deeper into the team - and closer to the man behind the mask they call Ghost - the lines between duty, trust and something much more dangerous start to blur.
The hunt for Makarov is on. But no one walks away from this clean.
