After surviving a terrible attack, Quinn Fleming has recovered in every way but one--her ability to retain new memories. Now, months later, it appears to the outside world as if the San Diego florist's life is back to normal. But Quinn is barely holding on, relying on a notebook she carries with her at all times, a record of her entire existence since the assault. So when she witnesses a murder in the shadowy alley behind the florist shop, Quinn immediately writes down every terrifying detail of the incident before her amnesia wipes it away. By the time the police arrive, there's no body, no crime scene, and no clues. The killing seems as erased from reality as it is from Quinn's mind . . . until the flashbacks begin. Suddenly, fragments of memories are surfacing--mere glimpses of that horrible night, but enough to convince Quinn that somewhere, locked in her subconscious, is the key to solving the case . . . and she's not the only one who knows. Somebody else has realized Quinn is a threat that needs to be eliminated. Now, with her life on the line and only her notes to guide her, Quinn sets out to find a killer she doesn't remember, but can't forget . . .
