Honestly, this book is probably a pain to read and forgettable unless you’re interested in the subject matter.
That said, if you’re interested in getting an inside look at the Google’s story, this is the book for you. It came out in April of 2011, just when Schmidt stepped out of the way, so it doesn’t address that shift, but otherwise, it’s the deep dive you’re looking for (if you are).
In the same vein, if you want the Facebook story, this is the one for you. It’s the vetted story, so watch for a rose-tint. No critique, no analysis, just the facts ma’am.
