Who are you at 16, if you can't remember anything about your life since you were 12? A brilliant exploration of identity and love for YA readers, by the bestselling author of Tomorrow, and Tomorrow, and Tomorrow.

After an accident that leaves her with partial amnesia, Naomi tries to piece together the fragments of the last three-and-a-half years of her life. She discovers that she has a tennis-champion boyfriend but can't remember him, is co-editor of the yearbook with a quirky guy who wears a smoking jacket, her parents are divorced, and she apparently hates her mother. She has friends who simply don't seem that attractive any more and, despite having meticulously kept a diary during the now-lost years, she only wrote about what she ate every day in it!

But when a girl loses three-and-a-half years, she gets a chance to reinvent herself. After all, who is to say that everything has to stay the same?
