Throughout all of Before I Fall, the idea that people are important come across strongly--which isn't always the case in YA fiction. I was so interested in seeing the changes the protagonist makes on each of her last days, in discovering how her priorities shift. And, more than anything, I wanted to see Sam's last day. Sure, you know the basic fact of how the novel ends. But it's the peripheral details and the human interactions that are more important. Oliver's style enriches such a thoughtful, well-plotted story.
I'd recommend this book for readers who enjoy YA realistic fiction (no vampires!), the strong characterization and interactions of the women's lives and relationships genre, or can't-put-it-down-until-I-know-what-happens quick reads.
