Survive, Consolidate, Protect, then Pillage

Eric Yang is a combat veteran of the Saudi war and a student at Denver University (DU). His goal was to reintegrate back into society. His service freed him from the mistakes of his past, his dedication pushed him to achieve more from life even with his disabilities, and yet, he struggled.

While not all scars from war are visible, Eric was given a cybernetic arm that even scientists in 2032 considered futuristic. An isolated semester at DU is disrupted by a dire warning from a top-secret source. The asteroid barreling toward Earth is an alien spacecraft with hostile intent. Eric scrambles to plan, consolidate, and form his team before their arrival.

The cringe is just too much

I get the impression the author is some Neckbeard beta male with an inability to navigate a normal conversation. I would be absolutely mind blown if they have ever experienced real flirting. I can put up with some pretty bad writing having built up a tolerance reading bad litrpg... But this steaming pile is too much. This book is like those bad music videos on YouTube that get lots of views because they are just so unbelievably cringy... Same thing here

I DNF this omnibus, giving up a little after 100 pages. I believe this omnibus is of one of the author's earlier series, but it doesn't look like a lot was cleaned up from early writer mishaps.

The biggest point of contention early in this is that the MC does a ton of tell, not show. Pages and pages of backstory he tells the various women he will presumably have in his harem going forward. It's a massive info dump that could have been handled better.

Plus, the MC's agency is overwhelmed by a woman from his past and now future, who co-opts his plans and accelerates them to meet the pending apocalypse. So instead of his being behind the 8-ball, he's out in front enough to manage the incoming events. The MC (and reader) are spoon fed everything needed to make the story a success, without the MC working out more than a preliminary plan that the woman stole and enhanced greatly.

The writing was just OK in this. Lots of single sentence paragraphs that should have been lumped together into a single paragraph. A few misspelled words, and poor grammar.

I really enjoyed this book. I've always been interested in apocalyptic survival themes. This one adds a new twist, in a Alien entity taking out most of our weapons of mass destruction and bringing down gates in all major cities that have portals to other worlds. Some of those portals open to hostile worlds and some open to friendly worlds. The core of the group were a brigade of soldiers that fought together in the collapse of Saudi Arabia government. That ended up being mostly a guerilla warfare of the worse kind, after the troops were abandoned by the United States government. As the governments of the world fell, various strongholds came about, with the group we are following being the most adaptive and with help becoming the strongest.
The book is a harem book and very well done. For the money this book is a very good value with quite a bit of story. The story ends with the possibility of more being added, however the author states that as far as he's concerned the books ended with a happy ending.

Apocalyptic Viking King

How does someone write a story about a guy with a crazy history. He was in prison and got recruited into the military At the end of the war he and his entire battalion of recruited convicts get left behind to die and have to fight, by any means, to get out. The world gets taken over by alien races. And they need to save humanity before it gets killed off for Earths resources and slaves.
I know, make him a fighter for all humanity and throw in a harem. Then give them the ability to live forever and become a place to welcome aliens to live and work in peace. Then rebel against the aliens that caused all the problems in the first place.
TADA thats this series...

This book is a combination of books 1-4 and the first 3 were fun and mostly exciting, but book 4 had really long periods of boring stuff and finally i just stopped reading. Now I'm writing the review vs finishing it...
*Yawn*

Again, the first 3 books were great, but I'm done with this series now!

Read in 2 weeks, just didn't want to pick it up any more.

Amazing series!

I was hooked and could barely put this series down while reading, often spending many a late night reading beyond when I should have been sleeping.

While the intro to the first book felt rushed, it was mixed in well with the urgency of events.
I love the portal system, the alien races and their technology.

One of the best series I've read with several character morality choices the author was not afraid to write and I congratulate him for.

Loved this series

Wasn’t sure of the premise but was happily surprised by how good these books were. Great MC with some awesome females to keep him on his toes and a well written story that kept you engaged. Ending left the ability to have more books. But doesn’t seem that there are more coming at least at the moment.

A riotous world rebuilding hot at times story set!

The first five chapters I really wasn’t sure what the book was about. It started out pretty erotic and heavy warfare. I just couldn’t put it down. I read the things straight through and it was great action and loving!!!
I hope you really like it, I did.

DNF.

Read like 265 pages and just got sick of the robotic prose. I was kinda sucked in at the start by the "veteran doomsday fantasy" pitch, but after taking a weekend away from reading anything I just can't stick with the robotic writing and incredibly short, chopped-up formatting. I'm sure someone will love this

Great series

Loved the whole series. The concept was refreshing. Alien overlords overreach and still get away. For the Crew. For the Community.

Really tried to finish this, made it most way through book 2 before I lost the plot. too tropy and generic for it to be worth another 8 hour investment.
