Rae Travis is having one of those days...First her computer breaks down at the top-secret laboratory where she works; then a tire blows on the way home, sending her into a border patrolman's cruiser in her in her driveway! Simon Kirk captures her interest, but his assignment is temporary. Someone in the area is ferrying terrorists between Florida and a nearby island used as a sanctuary, and Simon has to track him down. His news shocks Rae-she works on a project to safeguard airplanes from terrorist sabotage-but she never expects the danger to reach her. The next night, however, she and her brother find someone operating a secret radio transmitter, and their discovery nearly gets them killed. Rae's fears double when she learns that the technician who repairs her computer may be concealing her identity. If the project data fell into the wrong hands, the results would be devastating. Without concrete proof Rae is helpless to stop her coworker, unless she takes drastic steps that may cost her her job-and her life!
