A good continuation to the series, altough the author did have to break his back to give our group a surviving chance. Also by this point MC power is stretched thin, he has to manny things for him to fully focus and consolidate himself.

Yes!

I'm glad we're back into the Underworld.

We get more training montages, we get more blue magic and above all, we get more character development and world building.

Huzzah! Apollos.

While I enjoy the Codename Freedom story a lot, I'm glad the next one is going to keep rolling through Underworld.

Spectacular

Upon reading this book, I am again reminded why this is one of my top 3 favourite book series. Absolutely worth the read and I'm immeasurably excited for the next book in the series.

Fantastic, again

Once again another great read. The progresses and advancement reward the reader with more unique adventures of our group. I never saw the ending coming and could not be more satisfied. I will unfortunately be even more aggressive in asking for the next book!

Great book!

Love the addition to the series and it could not come soon enough. Already impatient for the next book. Would like to see a longer book in the next installation and giving more details to the leveling and classes would be enjoyable.

There were many parts during this where I figured I might give it a 5/10 or a 6/10 but eventually decided on 7/10 with that epic ending. Very much looking forward to the next book although it will probably just be more of the same.

One of my favorite series. Only regret is that I read it too fast and now I have to wait for the next book. I did not notice any errors and enjoyed every page.

Fantastic power ups

Fantastic power ups continue. The story just keeps getting better and better! The only way it could be improved was with more ranch dressing.

Bit of a Filler

This book is a bit of a filler. Quite a bit of grinding and one big fight. I like the direction the book is headed at the end though.

Getting boring.

This series has become to focused on numbers and levels. All the buff talk is getting old and the power levels are ridiculous. Fights are all one sided now, and that is just not any fun. I truly can not see what direction the story could take to alleviate this problem. The author has written himself into a corner of stats and there is no coming back from that.

This fourth book was sort of an odd one. Basically we got overwhelmed with character upgrades, a couple of boss-type fights, and an "interesting things are afoot, stay tuned" ending. We don't really see anything new in the Underworld. I mostly skimmed this one trying to find useful dialogue or something interesting and failed.

It really felt like the author was tired of the situation that he'd set up–the impending boss fight we all knew was coming–and just rushed through a bunch of character upgrades so that we could reach a place where the ending fight could be somewhat believable. There's some hint that something interesting might be coming in book five, and it's free on KU so I'll probably check it out, but I'm certainly not looking forward to it.
