Agent Rachel Stone is called back into the field for one last mission. Her target: Viktor Petrov, the Russian intelligence officer who once taught her everything she knows—and who she's never stopped loving.
Petrov has surfaced in Istanbul with a kill list of NATO's deepest cover agents. If his deal goes through, dozens of operatives across Europe will be executed within days. The CIA wants him neutralized. But Rachel has other ideas.
In the ancient corridors of the Grand Bazaar, old flames rekindle—and the deadliest game of cat and mouse begins. She must choose between her mission and her heart, before betrayal becomes the only currency that matters.
