'Escape' by Carolyn Jessop
'Stolen Innocence' by Elisa Wall.
They are really fascinating books about the Fundamentalist Latter Day Saints (those crack pots run by Warren Jeffs), and the trauma these woman went through to escape, and their whole up-bringings in the FLDS, including being a child brides, and the madness of Warren Jeffs.

I found 'Escape' to be slightly more moving than the other, although they are written by women of slightly different eras, there are many areas of overlap. Carolyn's shows the difference from the group when they were under a different leader, and how they weren't as nutty as they obviously are today. Very very interesting.
