Every year, as the anniversary of 9/11 inches closer on the calendar, Kit Capriol scans the memorials published in the New York Times. It's a simple thing to look up a name and phone number, and reach out to surviving family members who might still be yearning for connection with their lost loved one. After her husband went down in the North Tower, Kit scraped by as an actress. But now her daughter Zoey is in the hospital, bills are due and the acting work has dried up. Becoming a medium is almost too easy for someone used to pretending for a living. Now, though, something has changed. The seances Kit holds in her apartment are starting to feel unsettlingly real, and the intriguing man she met at a local bar could be more complicated than he seems.

As bestselling novelist Amelie Ferrar knows, an affair with a married person is like a work of fiction: a kind of spy story with its rules and customs, negotiations and compromises, and many private rituals. But like any spy story, there inevitably will be a betrayal: something will slip, someone else will find out, someone may even die. As Amelie falls deeper into her obsession with the man she loves --- and his wife --- the line between the fiction she writes and the reality she lives begins to blur...and the twisted ending to this story is one that not even she could have seen coming.
