Paraplegic young attorney Pen Wilkinson is unemployed and recovering from violent trauma when the FBI and police offer her an intriguing but risky assignment: working undercover at a defense contractor to investigate a young woman’s murder. As Pen, under a false identity, probes the company’s inner workings, she discovers infiltration by a foreign espionage ring, engaged in stealing top-secret defense technology for rogue nations. As the company’s security net closes in on her, Pen presses on, working frantically to learn the identity of the thieves, and of the young woman’s killer, before she meets the same fate.
