In 2025, rogue scientists and generals (the Masters) Are both the scientists and generals rogue? You might be able to eliminate the word generals and just say "rogue scientists and Masters" (then add a sentence to say what Masters are) After reading the whole thing, I think you could eliminate the "rogue scientists" part, since they don't really come up again (we assume the Masters are in some way scientific) control asteroids and extort 1.5 billion dollars from the United States I don't quite understand the connection between these two. The NSA advisor to the president, Dr. Will Port assembles a team: a coed NASA scientist, and the only black Italian in the FBI, Agent Chennaulti.So does this team consist of just two/three people? Cause that seems a bit small to call it a team. Maybe a task force? Or some other term? This may be minor The asteroid will impact New York City in ten days and they must stop it. Ah okay. This makes the first sentence clearer. If you can indicate this threat in the first sentence, it will help clarify a lot.
Port’s team flies to Moscow to investigate the death of a top scientist in the Russian Space Federation. This is random - how is it related to the asteroid? They track the death squads What are death squads? Are they literal death squads, or things specific to your story? to find clues leading to the Master’s lair. This makes it sound as if the Master is one person (if you want plural possessive, it should be Masters') Port advises President Ivanna Clout to announce a 100 million dollar reward for information leading to the arrest, conviction, or death of the Masters. They follow a bloody trail from Paris to Beijing to uncover an international conspiracy stretching from the Russian mafia to deep pockets in corporate America.
Will they catch the Masters in time? Agents usually don't like ending (or beginning) in rhetorical questions
Okay, a few thoughts:
1) your plot needs clarified, particularly how each event is linked to the next. You've got a lot going on, and you want to zoom in on only the most pertinent and main information.
2) you use too many names. Two or, at max, three names/characters should be used, or an agent is going to lose track and stop caring. In this case, it sounds like you'll want to focus on Will and the Masters.
3) I'm not getting much tension out of this - it could be because I was distracted by the plot, or because there actually isn't much tension. Something to keep in mind.
Overall, this definitely needs some plot clarification. Work out what's most important, and put that in alone. I know it's crazy hard, but keep trying :D
