Series background & context
The Jess Montgomery thrillers follow an intelligence analyst who keeps finding herself in the middle of very personal emergencies with global stakes. Jess is comfortable with data, classified briefings and strategy sessions, but her work keeps colliding with the safety of her own family.
In The Trident Conspiracy, a quick Saturday stop at a bank turns into a nightmare when her twelve year old niece Abby is kidnapped during a robbery. The abductors are not after cash, they want access to a secret invention tied to national security, and any call to the authorities could get Abby killed.
Jess is forced to rely on her own skills, the people she trusts and the quiet leverage that comes with knowing how sensitive projects inside the government really work. The story reads like a race against the clock, but it is also about how far an aunt will go when the system has no good answers.
The Patriarch Code catches up with Jess when her life appears to be settling down. She has a job at a Washington think tank, Abby is back home after the kidnapping, and marriage has added a fragile sense of normal. Then coordinated ransomware attacks begin hitting infrastructure around the country, putting lives, energy grids and covert technology at risk.
Drawn into the investigation, Jess becomes a target for the hackers behind the attacks, people who are willing to do anything to protect their profits and their secrets. The book takes her from briefing rooms to the heart of a conspiracy that tests her loyalty to colleagues, to her country and to the people she loves.
In Never Call Home, the danger cuts even closer when Jess's sister Rachel manages only a broken call for help from the streets of Boston before going silent. Following Rachel's trail drags Jess through neighborhoods marked by addiction and exploitation and forces her to confront parts of her family history she would rather leave buried.
As a group, the Jess Montgomery novels blend family drama with high tech threats, giving readers both emotional stakes and the thrill of unravelling complex plots. Read in order, they trace Jess's journey from analyst in the background to a woman who repeatedly chooses to step into the line of fire when no one else can or will.
