The Transformers Dark of the Moon novelization is out on May 24th so you can spoil yourself on all the juicy details of the film.
However the book’s plot synopsis may just tell us something about the plot that we didn’t know already. Rama Screen quotes the book flap:
All humankind was watching that fateful day in 1969. But only a handful knew the real mission behind America’s triumph in space. Now the treacherous Decepticons have set their sights on unearthing government secrets. The only hope of averting a crisis rests on the Autobots—yet who knows what remains in the shadows, hidden from man and machine?
Nope. We already knew all that from the trailer.
The mission to the moon is not as innocent and simple as we thought and they had an ulterior motive to find something, and they do, which implies the government knew about the bots back then.
Here I thought we were going to get something unique about the plot.
