I would recommend reading this book quickly, because it presents a rich and complicated story with two prongs: a Mormon history as background to the specific story of the murders of Brenda and Erica Lafferty. I had trouble finding time to finish it and returned it and re-requested from the library about three times, and while I enjoyed the book a lot, it would have been better to make the time to finish it right away because of the dense information within. Highly recommended!
