I will likely finish this tonight, after I get home!
Hester is a fantastic character. I also really like Galen's aunt, Racine, although we haven't really gotten to know her much.
Galen seems a bit shallow, but I think that's the point - his love for Hester will add depth to his character. I love the Underground Railroad connection, and the Michigan community where the abolition work is being done is absorbing.
