I have read a few books by Kathleen Eagle, and I think there has only been one or two that I ended up satisfied with. What The Heart Knows started out ok, and I was hoping it would just get better, but the flow was uneven and static at times. The story line was the best part of the book, but I just felt from beginning to end I had to force myself to get through it, I almost gave up on it, but I stuck with it, hoping it would get better however I only ended up in a spirit of frustration and how I seemed to get lost at times, and I felt like there could have more substance to the characters. I hope the next book I read from this author is much better.
