The Strongbox Chronicles

The clandestine Sicarii have hired Brandon Parker, the brilliant estranged son of Alisha's handler, to develop an artificial intelligence capable of enforcing their divine right to rule. No one, not even Brandon's father, imagines he can do it—not until Alisha herself faces one of the AI's battle drones in combat. It's suddenly a race between the CIA, the Sicarii, and Alisha's mercenary ex, to see who can keep—or steal—the AI for themselves.

When a mission goes sideways—again—thanks to her ex-lover Frank Reichart, Alisha's loyalties are called into question. Furious to learn that brilliant but treacherous Brandon Parker is back developing the next generation of his sophisticated artificial intelligences, assigned to desk duty, and sure that there are answers that only she can get to, Alisha is left with an impossible choice. She can follow orders, or she can strike out on her own to uncover Brandon's intentions, Reichart's secrets, and the hidden mastermind behind the game she's been drawn into.
