Unit One Books in Order

Unit One is Jasmine Cresswell's most direct move into spy-flavored romantic suspense. The three books, Decoy, Full Pursuit, and Final Justice, follow a covert government agency that works in the shadows, usually around politically sensitive cases where ordinary law enforcement cannot move openly.

At the center of the trilogy is Melody Beecham.

When Decoy begins, Melody is not a trained operative. She is an art gallery owner whose sense of self is ripped apart after her mother's death reveals that the man who raised her is not her biological father, and may be far more dangerous than she ever knew. Unit One sees value in her connections and the doors she can open, so the agency pulls her into its world through pressure, secrecy, and necessity rather than idealism. That gives the series a strong outsider-insider dynamic. Melody is learning the rules of covert work at the same time the reader is.

The romantic thread that carries across the books is her connection with Nick Anwar, sometimes referred to as Nikolai. He is the kind of hero Cresswell writes well: controlled, capable, and dangerous enough to unsettle everyone around him, including the woman he is trying to protect. Their relationship has to survive surveillance, manipulation, false identities, and assignments that demand emotional distance at exactly the wrong time.

By Full Pursuit, the series is operating at full thriller speed. Melody infiltrates a militant white supremacist group in rural Idaho while Nick follows corruption tied to high political circles. The pressure is not just physical danger. The missions require both of them to play roles and cultivate relationships for the sake of the job, which means the personal stakes stay as sharp as the external ones.

Then Final Justice turns the danger inward.

Someone starts hunting Melody for revenge, and Unit One has to figure out which of her past cases created the enemy now trying to kill her. The plot moves from one location to another, including Mexico, Washington, and New York, but the emotional question stays steady: can two people who live by secrecy trust each other completely when that trust is the only thing keeping them alive?

What makes Unit One distinct is the blend. These books have espionage energy, but they are still romance novels at heart. Cresswell keeps the action moving, yet she never loses interest in family damage, false identities, power, and the cost of living under pressure for too long. If you like romantic suspense with undercover work, political danger, and a central couple who have to earn their way to trust, Unit One is a strong pick.
