My overall opinion of the book is positive, and I'm giving it 4 stars. Here are the points I liked and those I think could be improved:

Aspects I Liked:

Engaging Plot: The story managed to capture my interest from the beginning and sparked curiosity.

Fluent Language and Narrative: The author's style was quite clean and professional; I didn't encounter any significant writing or narrative errors.

Successful Dialogue: The characters' conversations felt natural and were consistent with their personalities.

Satisfying Science Fiction: It contained surprising and fulfilling science fiction elements that did the genre justice.

Areas for Improvement:

Choice of Proper Nouns: Changing familiar names like Earth and Mars can create unnecessary confusion for the reader.

Pacing: In some sections, the plot progressed too quickly, which made it difficult to follow and could be confusing at times.

Timeline: The story's chronology remained somewhat unclear; I had difficulty following it completely.

Conclusion:

Despite these criticisms, it's very clear that a lot of effort was put into the book. For now, my rating is 4 stars. However, I should also mention that I read the book rather quickly. I might update my score if I notice different details upon a more careful reading. Happy reading to everyone.
