What is the author's tone in the nonfiction book, Help, Thanks, Wow?

Lamott’s tone when dealing with the subject of prayer is serious and full of awe, but it can also be sarcastic and satirical in places. It is as if she recognizes how hard life can be but also has learned sometimes the best one can do is make fun of it. In places in her story, Lamott takes on almost an irreverent tone. An example of this can be found in the chapter “Help,” when she refers to the cabinet that held her parents’ record albums and was treated by them as if it were the Ark of the Covenant, the most sacred of religious items.
