For disgraced CIA officer Dara McIntyre, a new assignment to monitor a troubled junior agent is yet another blow to her once high-flying career. Punished for her affair with a Jordanian spy, Dara is stuck in a dreary desk job at Langley headquarters when orders come down for her to assess whether recently widowed officer Caitlin Wolff is still fit to serve in the field.
Dara soon discovers that the grieving widow has dark secrets; Caitlin and her late husband, Jonathan, were running a lurid shadow operation. Convinced that the couple's unsanctioned acts led to Jonathan's murder, Dara investigates their final operation. Her mission to track the terrorists responsible for the murder and salvage her career takes Dara to the hedonistic playground of Dubai and the chaotic streets of Barcelona. But when the investigation takes a jarring turn, she can no longer be sure who--if anyone--she can trust.
