It tells the thoughts of the robots, well the writers interpretation, which I like.
The prequel was interesting since it tells of a secret ship that earth built and sent off with technology built from the discovered Megatron. And getting lost across the galaxy, and meeting up with the Decepticons and Autobots. A small battle and encounter with alien creature. And attempt to return to earth.
The book has additional dialogue, sequences in a different order, and thoughts of the characters.
Certainly the action of the movie can't be replicated in the book, but the dialogue and thoughts are much greater.
