** spoiler alert ** There is NO Risk from the real LIFE 99942 Apophis Spoiler: It appears that this story base on the 2019 PDC Hypothetical Asteroid Impact Scenario from the 2019 IAA Planetary Defense Conference (PDC). However, unlike the (PDC) that used an obviously factual asteroid 2019 PDC, the author uses unknown unbelievable chaos to convert the safe April 13, 2029 fly-by of 99942 Apophis to an impact scenario to use the book titles "Asteroid Apophis: Lord of Chaos." IMHO the author does not fully understand how asteroid observation is done in real life. This is not the book for anyone new to the subject of Planetary Defense
