Perfect for you if...

You love military romance with real stakes and protagonists who've been through genuine trauma and come out harder.
You want a heroine who doesn't need saving twice and a hero who respects her competence as much as he loves her.
You're after the first book in a series that builds a world of interconnected operatives and their messy, intense relationships.

Maybe not for you if...

You prefer romance where the central conflict is misunderstanding or miscommunication rather than actual mortal danger.
You need lighter fare without detailed references to torture, imprisonment, or the psychological fallout of black ops work.
You want a standalone novel rather than the first in a series that demands you keep reading.

About this book

CIA Agent Victoria Marshal survives torture in an Afghan prison and is rescued by Jacob King, a black ops commander. Their connection is immediate, though circumstances keep them apart. A year later, Jacob returns for the date they promised each other. As he recovers from his injuries in Victoria's care, their relationship deepens. However, their work in covert operations leaves little room for stability. When Jacob and his team disappear on a mission, Victoria re-enters the dangerous world she barely survived. This time, she operates on her own terms rather than following orders.
