About the spoilers (being a person who actually READ the book): this spoilers feed is extremely bias toward the movie being bad. it's obvious the guy hates the movie franchise, so dont let what they say push you toward the "bay raped my childhood" sector! (not to mention their depiction of
Starscream's Death Wasn't even acturate.)
Most of the book, is written through Optimus's point of view, any part w/ Optimus really, and IMO helped me come to grips with what actually happens, to to be honest, I was satisfied with the ending (and reading what OP was thinking throughout the whole conflict and resolve helped too).
Basically in short, I finished the book in less than 24hrs. It is a page turner and you will lose track of time while reading it. Strongly suggested that if you're going to read the article for spoilers, invest a little time and actually read the thing.
And yes this is coming from someone who did have issues with the story and the previous two films, and no.. I'm not on Hasbro's or Bay's payroll
