Five months ago, an accident left Diana Sparrow injured and missing a few months of memory. Now she's having recurring nightmares about that night. They feel so real and she's left questioning. Did she hit something? Or someone? She can't turn to her former best friend Val, who's been sleeping with Diana's husband Jonathan for months, but she can find some comfort in newcomer Cole Pelham. The closer they become, the more Diana wonders how Cole might be connected to that night. And how everyone else is too.
