Seven Rules of Time Travel (2020, Independently Published) 2 stars

Review of 'Seven Rules of Time Travel' on 'Goodreads'

2 stars

He spends way more time of the story on how to prevent 9/11 instead of focusing on the end of the world.
Even his father and the scientist mention to him this is nothing when compared to the supernova explosion, and still the author spends most of the story on it.
