It's an all right book, that tries to touch on the process of becoming newly religious with some amount of candour and insight. The problem, for me, is that as a person brought up religious, I see quite clearly all the gaps in logic and jumping around for reasons that don't really ever make any sense which the author chooses not to address, or cannot address, or something.
For example, there is a very long, quite frustrating to read, to me, dialogue, between the newly-religious protagonist and an ex-Torah scholar, non-religious now man, who claims she stonewalls him. The chapter ends with her parents being unwittingly impressed, and the man she's arguing with presented in the worst possible light, but the truth is that to me, as a reader, she absolutely does stonewall him, she doesn't make a single cogent argument and, as a straw man for her cause, neither does he. It's all quite ridiculous and sad.
In fact, this lack of insight and obvious writer's bias do permeate any and all things written in the book. It's clearly a record of personal experience, and while the author makes the protagonist's disgust with the life she leads comprehensible and clear to us, she fails to do so with the process of return.
It's all right, though, reads fast, actually has a story, and the language isn't grating, so I don't regret the time I spent on it.
