Honestly, I feel like two stars is being generous, but because I understand the overarching intent of the book, I'll have some grace.
This book is very specific for churches who are attempting to launch "missional communities" as their model for small groups. The idea is that a group of people would choose to do life together as a family with a common mission to love a particular people group/part of the city in some functional, tangible way. The books is primarily targeted at MC leaders, and honestly, it's a great model. The book functions as a sort of handbook or manual for getting started. However, the book is so poorly written that it is distracting. The typos and blatant errors were innumerable, (we're talking multiple errors and typos on every single page). The whole entire time I was reading it, from beginning to end (so like, all of 2 hours?) I kept asking myself "WHO EDITED THIS THING?" Answer: no one. No one did.
BUT- If your type-A self can get past all that, the book describes well-enough what a missional community IS. And if in fact you had no idea what one was until you picked up this book, it could probably be useful for helping you think through the ways, functionally, to get started. I appreciate the aim of this book, I just think it was executed poorly.
