Forever and For Always — Jerry J. Davis

In this fourth book of the Bridge of Eternity series, the soul of Jon August returns from the afterlife once more, but this time instead of searching for the Holy Beer, he has a much bigger, and more important challenge: find out who broke the fabric of reality itself, and fix it before it's too late! So what does chaos, infinity, Albert Einstein, Nikola Tesla, and beer all have in common? THIS BOOK.
