I thoroughly enjoyed this book for the characters, the story and for the realistic and finely described period details of the post-civil war era. Nell and Will are very interesting characters whose prior lives are unfolded as the narrative progresses. These are strong, sympathetic and yet somewhat flawed personalities that seem totally lifelike. The writing quality is excellent and allows you to enjoy the flow and style as well as the story.This is a first installment that will definitely grab you and make you want to read others in the series.
