This was a fun little read. McConnel did a nice job comparing the fear of witchcraft with modern day Wiccan beliefs. Lou's soul searching came across as real and believable. Ultimately, her search for herself leads her to find more than she ever hoped for.
I really enjoyed the back and forth between the present and the past. In fact, I believe I enjoyed Isobel's story more than Lou's. I wanted more of that story, the details, the every day. Kudos to McConnel for her twist ending. You expect one thing to happen, because that's what always happens, but then something else happens instead. *sigh* It was great in my opinion.
The story made me wish I was in Scotland, but then again I always wish I was in Scotland. This book took a bit for me to get into, but once I did I enjoyed it. However it's been a week since I read it and I don't remember a lot of details.
I give The Burning of Isobel Key by Jen McConnel at 3.5.
