DNF for me, at just 20% ... I wasn't really in the mood for this, but doubt I ever will be. Super snarky, over the top attempt at humor that just annoyed me.  But the real issue was that it was mostly about books that either I haven't read yet but want to (and I don't want any spoilers, even as simple as featured here), or books I'm not familiar with, and if I don't know the book, the "letter to the book" really isn't something I "get" or enjoy. 

Two sections  1) Books - the Letters   2) Special Subjects
MANY chapters (headers, no chronological listing, so I don't know how many, but LOTS, although most were very short, just a page or two) in each section. 

I'd heard about this in one of my Facebook groups, I'm sure it was a glowing recommendation  - but this just didn't do it for me.  Library borrow, audio and Kindle copy. I didn't love the audio, maybe would have done better with a quick read of the Kindle copy on my own? I'd started with audio and given up already though ...
