You are in for a treat. I just read an interview with the author, Delia Owens, done by Amazon. You shouldn't read the interview though until after reading the book. The book has been a best seller in the U.S. for 10 months now and it still is ranked #1.
Owens was afraid that no one would read her book. She is overwhelmed that people are enjoying the book. Turns out it is the most popular debut novel in recent memory.
It has similarities to "To Kill A Mockingbird" in writing style (at least to me).
