I have just found out about a new book.  Hot off the press. We may want to think about this an adult ed or small group resource. It is available from Amazon in paperback or kindle and an audio version is coming soon.  You can also buy directly from the author, and with that get a free downloadable pdf version.  Or…. if you want to get the pdf for free or whatever you think is a fair price you can go to this link.  Amazing.
