Interesting concept. Red Dot is about the reactions of humans in the light of discovering there is a spacecraft from another planet coming to Earth. It's about what countries, governments, and people might do, from the extreme to the simple things.
The story is well written, however, the third person omniscient POV didn't do it quite well for me. It felt a bit cold and on the verge of being objective. What I mean is it lacked the closeness of the characters. I wished we would have been more in their heads. Not that we didn't get their thoughts, because we did, just not as much as I would have liked. To be honest, it was mostly at the beginning though. After a bit, it gets better. Of course, as a disclosure, I must admit to being a fan of the first person POV or third limited.
We don't get much of the ETs but we do get a glimpse of them. The author didn't leave us hanging with a 'So what or who were they after all' for which I greatly appreciated.
Over all, I'd give a five for the story, and a three for the characters. Nonetheless, this could make a great movie.
(Edited: Forgot to add that I didn't read the paperback version but rather the Kindle version, but there is no other version to choose here.)
