The Last One in the Universe by Chrissie Perry
Girl vs. the World is a fun, true-to-life series about navigating high school, first crushes, and the ups and downs of adolescence.
Hazel's friends are super cool, but she feels like a fraud. She doesn't have her period yet and she's never been kissed, and she's not confident or pretty like her friends are, either! So what should she do about her crush on Leo, who's sweet and funny but in the year above? Maybe it's time to take matters into her own hands ...
Refreshingly honest and deliciously heartwarming, this series is perfect for readers aged 10 to 13.
