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

The book was written in first person from Todd's point of view. Because of this, the reader had a clear idea of the inner workings of the family. Instead of merely hearing an account of the trip to heaven, the reader could understand the pain and anguish the family went through as they lost their child slipping away from them. The reader could also experience the wonder and awe, and even a bit of doubt that was quickly overcome as Colton's experience unfolded before the parents.
