What is the fine-grained topic of the following text: If you’ve spent time in bookstores, you’ve probably seen the Heaven is For Real book on the shelves, a book that details the totally true story told by a four year old that details his trip to Heaven when he was under during emergency surgery, a trip that is oddly consistent with what he would have learned in the church of his pastor father. Only return the topic.
A four-year-old's experience of visiting Heaven during emergency surgery as told in the book "Heaven is For Real".
