Thanks for allowing me to review "Babylon Has Fallen", @YahRuach !

Cover:

The cover exhibits the title and story to some extent through the dark shadow cast by the sun which causes the gloominess of the environment beneath it. The setting of the sun and the dimming lights as a result seems to mark an end to the previous normal and illustrates darker times ahead as stated in the title.

I would only suggest that the buildings in the cover be not so well-structured. If an area has fallen and you're trying to portray it through the cover, I believe that there should be at least an obvious form of chaos. I recommend dilapidated buildings together with the darkness you already have instead to better portray the fallen city of Babylon.

Blurb:

It certainly contained all the interesting characteristics of an apocalypse... well, fun for the reader, NOT the characters, that's for sure. I was looking forward to finding out Jonah's role in the midst of all this anarchy and why he wasn't slaughtered like everyone else in his village.

I suggest, however, that you can use another term  to describe an attractive woman instead of "hot chick". It may seem vulgar and not sit well with a potential reader who takes a first glance at the blurb.

Plot:

Each chapter is really portrayed with impressive imagery. There is the mention of the normal times, our reality, which gives better knowledge of their current times in theirs through suitable contrasts.
The plot does not fail to display the chaos which would have been anticipated after reading the blurb.

There are multiple stories from the many characters told which got me thinking about their relevance to the novel. I think you should make it clear what exactly all this would be linked to Jonah soon because he seems important.

Characters:

Jonah really surprised me with his history, I'm not going to lie.

With the many characters, one begins to hope for some form of humanity in any of the characters and it's pleasantly shocking to see it in those you don't expect; like Eva.

I'm optimistic on how the roles of the characters would play out in the novel.

Grammar:

There were very few typos and grammatical errors. You can crosscheck your punctuations as well. I think maybe aside the normal spacing between the paragraph, you use a sign or line or something to create a divider when a different scene is being used in the same chapter.

Generally,

I honestly don't know why I don't read sci-fi books much because there are clearly good ones like yours out there! I genuinely enjoyed reviewing this book and I wish you all the best.

Thanks again for requesting😊❤️! Hope you're all having a good day or night.

Look out for my last review!
