Nora Baron returns! The CIA's most unlikely agent faces her deadliest challenge yet among the islands of the West Indies in this nonstop thriller from USA Today bestselling author Tom Savage.

A typical middle-aged couple on a first-class Caribbean cruise: That's what the CIA needs for its latest mission, and husband-and-wife agents Jeff and Nora Baron leap at the chance. All they have to do is observe and report on fellow passenger Claude Lamont–a shady French businessman who's attracted the Company's interest–and his mysterious wife, Carmen. It's an easy assignment . . . until a shopping trip at a port of call turns deadly, and Nora and her husband are forced to split up.

After Carmen abruptly disembarks, Nora follows her to Martinique while Jeff remains on board with Claude. But the beautiful French island holds a shocking secret. One American agent has already vanished from the area, and Nora soon learns why. A shadowy international terrorist known only as Diablo has come to the islands for a sinister purpose. With Jeff out of contact, Nora investigates on her own. But Diablo is waiting for her, and now Nora Baron is trapped between the Devil and the deep blue sea.
