This didn't really get good until Harriet went to the North, which doesn't happen until the last 50 pages of the book. There were inconsistencies in her story and things that didn't really make sense to me (this review
contains spoilers, but details the things that stood out). Sometimes she talks around things that happened instead of giving a clear idea of what actually happened. It's written in flowery, educated language that was a little tiresome.
Once she escaped North Carolina, the pace picked up, and the story made sense. Overall, it was a decent read. I was expecting it to be better than it was.
