Radical: Taking Back Your Faith from the American Dream

This David Platt book is a compelling, yet not easy, read. It has challenged me to re-assess my faith (and the fruits of it) on nearly every page.

I'm curious to know if your small group (or someone's you know about) has used the Radical Small Group Study that goes along with Platt's Radical and Radical Together books? I'm interested to know if you had good results and any feedback you might have for others considering going on this journey with a group.
