My favorites of visitors to heaven stories  are by a gal named Anna Roundtree... her wonderful books are "The Heaven's Opened" and "The Priestly Bride."   The naratives of the books are short around 120 pages but the
references to the narative is just as great as the body of the text..  I recommend reading the text from front to back and then re-read it and go to each reference...  As I read the accounts of her experiences, I would say to myself
"I don't remember that in the bible" but after reading the references I would say... "it really is there!!"  So I highly
recommend these two books...
