What a confusing book. Its length is typical of middle-grade (175 pages), and protagonist Lucy behaves like a typical twelve-year-old. The problem: Lucy is actually sixteen. She's caught in a love triangle and will have to choose between her suitors (and marry one of them) fairly soon, and yes, her dithering composes a large portion of the story.
Modern ideologies, especially the stereotypical Independent Woman Ahead of Her Time, creep into this historical novel rather often. The moralizing is heavy-handed even for middle-grade fiction but really doesn't work as young adult. I know, this isn't a young adult novel: for proof, see the cover. And the word count. And the existence of a subtitle. (And the back cover, which says reading level 5.0.)
I don't understand why the book was written this way, why Lucy is sixteen-going-on-twelve. Why the main secondary character Cass is a nineteen-year-old, escaped slave who is pregnant for the third time with a child of the white master who rapes her. Why so much of the book involves Lucy complaining about things like the weather and having to remind herself that Cass's life is worse than hers.
All that said, there are seeds of a good story here. An effort was made toward nineteenth-century diction. The devout faith of the Quakers--the cultural faith of all the characters--is an appreciated, historically accurate touch. Doubling the length (but not the dithering), aging the character behaviors appropriately, and deepening characterization past types might have made it worthwhile. As it is, too many things feel groundless or rushed. 2.5 stars.
