There is [yet another] book I've read before that I'm reading again. It's called Suddenly, by M. E. Tudor, and it has some interesting features.
Firstly, it's about a cheerleader who unexpectedly falls for girl with a rough past (who 'runs with a bad crowd,' as they put it), but who has turned over a new leaf, and walks a dramatically new road. Her past crowd begins to pester the main girl, and the other girl defends her very vehemently. I like these two characters very much, and, of course, that's half the battle of writing a successful story: to create believable, engaging characters. They have to be so convincing that the reader just can't abandon them! I've written a few stories, as you know, but the main one—the extended story of Helen, split into a half-dozen separate pieces—was so specialized, that only a few readers could relate to the main character of Helen, and I sort of have up. (The subsidiary characters were a lot more relatable, and I focused on them.)
Secondly, there's the matter of voice. The story is written in the first person, the cheerleader. But the speech of the narration is that of a very middle-class teenager. I've gone online, and read what Ms. Tudor has written in a lot of places, and in every case, the grammar, the vocabulary, the content of what she writes is most definitely adult, and humorous, and very different from what that cheerleader says in the book. I've tried that—to write a first-person narration in the voice of a character—and it is very hard indeed! (That's how I wrote Yraid, and I don't think I pulled it off. Another story like that, Eyebrows, remains unfinished.)
The girl's (narrator's) mother is problematic. She comes from money, and has very bourgeoise, superficial values: money, clothes, family, real estate, cars. The cheerleader herself is far more down-to-earth, compassionate, values, streets ahead of her mother. Her father is a much more reasonable person, and supports her friendship. You have to wonder how the child of such a pair of parents could acquire such liberal values. In my experience, most of our values are inherited from our parents. Anyway, in the story it's a synthetic family; the father is a step-father.
Well, I encourage you to read this story; I have trouble inserting links, or I'd give you one. It's on Amazon (though we 'antifa' people hate Amazon on principle).
