There are two good things about this book: it's about a sixteen year-old girl figuring out and accepting she's asexual, and the romance is biracial (it does not, however, inform or in any way impact the black character, their relationship, or the story).
Further than that, the story is simple, with little unrealistic drama, and easy acceptance from the people who matter. Even the homophobic character faces some consequences at school. Sadly, the main character agonizes for months over her "brokenness" without even thinking of googling it, but changes her mind in three days once exposed to the idea... though the way this (the love interest introducing the concept of asexuality to the main character) was handled was respectful.
All in all, a short and basic story, written with basic storytelling and writing skills, featuring basic characters (not unlikeable, but not remarkable).
