Coincidentally, like the last book I read, this one is by an author who left (escaped from?) an insular community in England and then returned to it. The Killing Jar took place in crime-ridden Nottingham, and Disobedience in Orthodox Jewish Hendon. I say "coincidentally" because I found Disobedience browsing in my new branch of the NYPL, Hamilton Fish. Moving is traumatic; I'm going to miss Tompkins Square.
Moving was not traumatic for Ronit Krushka, who left the Orthodox community over which her father presided as Rabbi. She fled the country for New York and rarely looked back, until her father died. Disobedience is a story of making peace with childhood demons and lovers. Like Monaghan with Nottingham, 
There are also some interesting revelations about same sex lovin' in the bible! "And the men kissed each other and wept with one another until David exceeded. And Jonathan said to David 'Go in Peace. What we two have sworn in the name of God shall be forever.'" p.98
I want to warn you, though, that the book gets off to a slightly rocky start. There are two different typefaces, one for Ronit's voice, and one for the omniscient narrator. I don't know about you, but that sort of thing puts me off. It's better than pages of italics, though! Also the first few Ronit entries are a little chick-lit sounding. Don't worry; that doesn't last. I am so psyched that I found this book on the shelf!
