Let Over Lambda: 50 Years of Lisp: any thoughts?

The book Let Over Lambda: 50 Years of Lisp by Doug Hoyte (2008) seems good but I haven't seen it recommended or discussed much. I ordered a copy thinking it was some overlooked vintage classic, then realized it's a self-published work.

The book is on its way to me and I read a few reviews. And yes it's opinionated, but the author regrets the language.

Still, since the book is so intriguing, if you have any thoughts I'd be happy to read them.
