Mercenary Books in Order

Mercenary is one long crime-romance chase told across four books. At the center is Verity, the daughter of a ruthless mob boss, and X, the assassin sent to kill her. That is a strong hook already, but what gives the series real momentum is that the two are forced into uneasy alliance almost as soon as they meet.

Verity is not a passive target. She is trying to survive witness protection, save her younger sister, and stay one step ahead of the father whose world she is trying to escape. X is deadly, controlled, and deeply inconvenient, because once he stops being only a threat he becomes the one man who understands how dangerous her situation really is. Across The Choice She Made, The Lie She Told, The Trust She Gave, and The Trap She Faced, the story moves through betrayal, pursuit, prison, and the ugly reach of organized crime.

This is very much one continuous arc.

The books are short and fast, and they work best when read back to back. If you like romantic suspense where the central couple spend as much time running and fighting as they do falling for each other, Mercenary is one of Farrar's cleanest binge reads.
