What is the author's tone in Heaven Is for Real: A Little Boy's Astounding Story of His Trip to Heaven and Back by Todd Burpo?

The tone of this book is subjective. Heaven is for Real: A Little Boy's Astounding Story of His Trip to Heaven and Back by Todd Burpo with Lynn Vincent is a narration of the events that happened to the Burpo family. The topic was serious, but anecdotes, background information, and humor made it an inspiring read rather than a dry, dull depiction of events.
