"On a cold, rainy morning, finance journalist Ally Linden arrives soaked to the bone at her Manhattan office, only to find that she's forgotten her keycard. When her boss shows, he's shocked to see her--because, he explains, she hasn't worked there in five years. Ally knows her name, but is having trouble coming up with much beyond that, though after a trip to the psychiatric ER, she begins to piece together important facts: she lives on the Upper West Side; she's now a freelance journalist; she's married to a terrific man named Hugh. More memories materialize and yet she still can't recall anything about the previous two days. Diagnosed as having experienced a dissociative state, she starts to wonder if it may have been triggered by something she saw. Could she have witnessed an accident--or worse--had something happened to her?” Thriller
