I really enjoyed the story.  I have little knowledge of Judaism, but that was not necessary.  Reva had grown up in a less restrictive  Jewish religious atmosphere but with marriage to an orthodox Jew and with two boys, she embraced the tenants of her faith, with her whole heart and even as a widow, kept the faith.  She lived in an tight knit community centered around a school, and was one of the few who had outside experience.  When there was a brutal rape, she ended up being the one who worked best with the police.  The sense of community and its isolation from the mainstream plays a large part in the story.  Some of the locals are indifferent, some curious and some hostile to this community. There is mystery and even murder and hints at a blossoming love story. I found it a satisfying read.
