Oops, I might've forgot to mention that I finished this book a couple weeks ago *sheepish grin*

Update: All right! I'm just going to do an over-arching review of the trilogy, so there may be some minor spoilers (I promise to do my best not to give away too much :) )
First off, I just want to say I love Gran in this series! She's quite the spitfire. And Daisy's amazing! I just want to hug her. She's such a good friend! (And she calls Austin 'Dustin' instead of his actual name, and that was so funny XD).
I haven't read a ton of Christian End-Times stories, but this trilogy was a really intriguing premise. The author's take on who Mystery Babylon was, surprised me (and while I don't fully agree, I still enjoyed hearing her make her case.) Also, the author did a good job capturing the different worldviews of each country (Russia, China, and the U.S). It felt like a well-researched story, and all the details made the setting come alive.
That being said I felt like, personally, the whole trilogy could be condensed into one book. Parts of the writing felt dry, and sometimes it dragged a bit (although switching between viewpoints did help to heighten the tension in some areas, which was a really good idea. I just felt like it was done too much, so maybe that's why the story felt strung out.)
Also, I didn't fully connect with Sierra or Austin. Their arcs weren't very believable, and it felt rushed at the end. The only character I was truly rooting for was Wu-Ying (*clutches heart* He needs a hug too, poor man.) Perhaps the reason why I didn't get super invested with a lot of the characters is because there was no definable hero/protagonist of the story. When I first started it, I thought it would be Sierra, or at least the majority of the books would be centered around her; but not really.
On the other hand, I'm very much a character-driven story person, and this was more centered around the plot. So, actually, it's probably just a personal preference sort of thing.
All in all, if you like Christian sci-fi/End Times stories, I think it'd be worth checking out. (Some minor content warnings would be use of swear words and torture, though not super detailed.)
Three whole stars for the entire trilogy!
