You could say MOSTLY GOOD GIRLS is about high school and its stresses. Or prep school. Or friendship. Or first loves. But I like to say that Leila Sales' debut novel is about growing up... the growing up that each and every one of does in high school, only more entaining and witty than our own lives.Violet is definitely her own person, but most girls will relate to her in one way or another. She's competitive, stressed about school, often feels second best, can't help but compare herself to her best friend, has been in love with the same boy for years, and she feels totally and completely overwhelmed the majority of the time. At multiple points throughout the novel, I found myself commiserating with Violet as she confronts the changes and challenges in her life.What I enjoyed most about this novel is that there really wasn't one big issue. While I love novels that confront big, difficult topics like the death of a loved one, teen pregnancy, drug use, etc, etc, MOSTLY GOOD GIRLS took a different approach. There is some talk of bullying, but, for the most part, Violet is dealing with everyday, "normal" issues. Like grades and the distance that sometimes forms between previously inseparable best friends. Novels about those intense topics are needed and always appreciated, but there's something about Violet's story that pulls you in, even without those shocking twists and gutwrenching material.MOSTLY GOOD GIRLS is a funny, relateable first novel and I can't wait for more from this talented author!
