Private Investigator and reformed spy Ronnie Tracey lands in a tricky spot when she detains a woman snooping around her friend Emily's house—only to learn her Nana was hired by the same woman, Kerrin Costa, to find a missing cousin. But Costa's no ordinary client; she works for SIDE, Argentina's Intelligence Agency. Fearing Costa has sinister plans for Emily, Ronnie sends a partner to watch over her at the bookshop. When Ronnie arrives, Jenn is unconscious, and Emily is gone—abducted by two men. As the investigation deepens, secrets from Emily's forgotten past emerge, and the situation spirals into a tangled web of foreign agents and dangerous truths.

In a world of shifting lies and buried truths, Ronnie is racing against time to save her friend, Emily. But Emily doesn't even know the nightmare she's caught in—or why they're all after her.
