Marlene loves three things: books, Her cool Tía Ruby and hanging out with her best friend Camila. But according to her mother, Paola, the only thing she needs to focus on is school and "growing up." That means straightening her hair every weekend so she could have "presentable good hair." But Marlene hates being in the salon and doesn't understand why her curls are not considered pretty by those around her. With a few hiccups, a dash of embarrassment, and the much-needed help of Camila and Tía Ruby--she slowly starts a journey to learn to appreciate and proudly wear her curly hair.
