Absence of Faith, a book that chronicles 16 deconversion stories, is available for purchase and as far as atheist based books go, it is a great concept.
The book was written by MS Pearce (who writes the blog The Tippling Philosopher) and Tristan Vick (who writes Advocatus Atheist) with a foreword by Jeremy Beahan (of Reasonable Doubts).
My deconversion story is detailed in it as well and the first review of the book mentions it. It is humbling and exciting to note that some people find my story moving in any way.
Please check out the review below and if so inclined, check out the book:
