This slim book is basically a published version of a sociological project report, but it was written well and readably for what it is. It focuses on people who have left "EPC" (meaning, Evangelical, Pentecostal, and Charismatic) churches and the different stages of faith development they go through both before and after leaving. Contrary to stereotypes, these "leavers" are not necessarily ignorant or inexperienced in their faith, in fact they're often leaders and have done extensive theological study. They also don't necessarily abandon their faith as a result of leaving a formal EPC church. Often they go through a period of questioning but many come out on the other side with a deeper faith even though they haven't gone back to the same kind of church, or church at all. I found it deeply validating and personally relatable through the first two-thirds of the book. Also hopeful and encouraging. The last chapter or two, which focused on postmodernism and post-church groups, tended to lose me a little bit and even read slightly dated. But there were still some good ideas even in those chapters, about churches making way for people who have really deep questions and doubts in their faith.
