Calculated Deception (Book 1)

Dr. Ree Ryland is an engineering professor who loves her job and plays by the rules. Her life is reassuringly predictable – until an enemy hiding in plain sight decides her squeaky-clean reputation is the perfect cover to commit a crime.

When Agent Parker Landon and his FBI team discover that someone at the university has been procuring military-grade hardware by disguising it as test equipment, all evidence points to Ree. After the FBI intercepts a shipment that puts Ree in the clear, Parker is forced to tell her that she's being used as a pawn by an unseen enemy. And now she's in that enemy's crosshairs. Ree turns down the protective detail offered by the FBI and insists on using her inside knowledge to help with the investigation. Parker is leery of bringing a civilian on to the team, but he's surprised at how much fun he has working with Ree, even as he tries to keep her out of harm's way.

Parker, Ree, and the FBI team find increasingly worrying evidence that someone is quietly acquiring everything they need to cause destruction on a massive scale. Now, they must uncover the motive and identity of the killer hiding among Ree's friends and colleagues before it's too late.

Calculated Contagion (Book 2)

Dani Christensen is a vaccine researcher who has spent her career proving she is more than just the daughter of the company's CEO. However, as her accomplishments in contagious disease research grow, the wrong people begin to notice. When Dani is isolated from her colleagues at a well-regarded conference in Europe, she is kidnapped and taken to an isolated camp in the Carpathian Mountains.

CIA officers Cam Mitchell and Tyler Scott are sent to observe a suspicious group of armed men in rural Romania. When Cam sees Dani being brought into the camp against her will, he and his partner rescue her and bring her safely back to the United States. The CIA initially believes Dani was kidnapped for ransom, but they soon realize her kidnapper has followed her back to her lab. Now, the CIA must work with their allies in the FBI to catch Dani's kidnapper before he releases a potentially deadly contagion for his own political gain.

Calculated Sabotage (Book 3)

CIA operations officer Quinn King will do whatever it takes to find the person who killed her partner. She follows the evidence to Innovative Rocket Technologies, a start-up company and current darling of the rocket world. Their most recent launch, however, ended in an explosion that Quinn believes is connected to her partner's death.

The CIA sends Cam Mitchell to provide backup for Quinn — and to make sure she isn't too emotionally invested. With Cam watching her back, Quinn embeds herself at IRT. She soon discovers there is more to the failed launch than IRT has shared with the public. And someone has a vested interest in keeping that information under wraps.

When the CIA finds new evidence that someone is actively sabotaging the next launch, they call in Parker, Ree, and Mike from the FBI to help manage a growing number of loose ends. However, once Cam and Quinn realize why the rocket is being...
