Memoirs of a Teenage Amnesiac — Gabrielle Zevin

If Naomi had picked tails, she would have won the coin toss. She wouldn't have had to go back for the yearbook camera, and she wouldn't have hit her head on the steps. She wouldn't have woken up in an ambulance with amnesia. She certainly would have remembered her boyfriend, Ace. She might even have remembered why she fell in love with him in the first place. She would understand why her best friend, Will, keeps calling her "Chief." She'd know about her mom's new family. She'd know about her dad's fiancee. She never would have met James, the boy with the questionable past and the even fuzzier future, who tells her he once wanted to kiss her. She wouldn't have wanted to kiss him back.

But Naomi picked heads.

After her remarkable debut, Gabrielle Zevin has crafted an imaginative second novel all about love and second chances.
