Tiago Dall'Igna reviewed Seven Rules of Time Travel by Roy Huff
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.
