Somewhere between 3 and 4. Very similar to the first, and treads dangerously on "old man shouts at cloud" territory with the ranting. The story is sort of fun though.

You're not going to be going omg, that was a life altering experience after this, but you might go, that was a enjoyable experience.

EDIT: Originally I wasn't going to mention this in this review, because it's a big spoiler, and like audiobook only, but that's what spoiler tags are for right? There is one fanatastic scene in the audiobook of this which might be worth reading (listening to?) the book on its own for, where M.K. Gibson makes Jeffrey Kafer break the 4th wall. And not just like a "oh dear listener" type shit, no a total break, and it's pretty hillarious (and childish) and great.
