"When Mallory discovers that her boyfriend, Jeremy, is cheating on her with an online girlfriend, she swears off boys. She also swears off modern technology. Inspired by a list of goals her grandmother made in 1962, Mallory decides to "go vintage" and return to a simpler time (when boyfriends couldn't cheat on you online)."
Defy by Sara. B. Larson.

The Perks of Being a Wallflower by Stephen Chbosky
"a story about what it’s like to travel that strange course through the uncharted territory of high school. The world of first dates, family dramas, and new friends. Of sex, drugs, and The Rocky Horror Picture Show. Of those wild and poignant roller-coaster days known as growing up."
