The book is called “The God Who May Be,” and it’s by Richard Kearney. It’s quite dense; however a good non-dense introduction to it may be found in an episode of the CBC-Radio programme called “Ideas” of the same name as the book, possibly podcastable but definitely mailorderable.
I can only recommend it as having been a very interesting stop-point for me. It may not deliver you the same benefit. But I hope it might. P.S.: learn French.
