What is the author's style in The Hiding Place by Corrie ten Boom?

Corrie Ten Boom recalls the story in first person point of view. She tells the story as she looks back over important events in her life. Though she now possesses much more knowledge than she did as the events happened, some events remain unexplained, such as the whereabouts of Kik. Though she shares the horrors of her time in the concentration camp, ultimately Corrie intends to encourage her reader with the story of her survival. She expresses her never-ending hope that all things happen for a reason.
