Loner Series #4

Guardian of the Dungeon

Rate this book
Andrey has finally obtained the first of the five swords he needs to complete the Goddess of Fate's quest. Now his path is taking him to the subterranean city of the Gremlins, Arkem. Gremlins are unpleasant, rascally creatures, with a twisted system of logic and a penchant for limitless chaos. So trying to negotiate with them is always fraught with danger. Fortunately, they happen to worship the mechanisms of the Ancients, which are somehow, mysteriously, connected to Andrey’s hidden "Slider" class. This means that Andrey has a chance of recovering the second sword after all. Everything gets complicated, however, when a breach to the Inferno opens in Arkem, through which comes an invasion force headed by none other than Lamia, the Succubus who dreams of shredding Falk into tiny little ribbons.

And the real world is full of problems, too - mysterious people keep trying to kidnap Andrey, and he's forced to use his newfound abilities to protect himself. As if that weren't enough, the game menu is now popping up in real life, which is making him question his own sanity. But the main question are there other people who've acquired powers from the game like he has? And what will it all lead to in the end?

Im vierten Band der Einzelgänger-Reihe reisen wir ins unterirdische Reich der Gremlins, und diese Kinder des Chaos passen zu Falk und seinem gepachteten Pech wie die Faust aufs Auge. Außerdem sind wir - nach dem die letzten beiden Bücher noch einen ordentlichen Anteil in der echten Welt hatten - diesmal fast nur im Spiel unterwegs, wo das Tempo ordentlich anzieht. Neue Geheimnisse werden aufgedeckt und eine alte Bekannte taucht wieder auf...das alles ist so chaotisch wie unterhaltsam und liest sich einfach wirklich gut weg, und ich bin sehr gespannt, wohin all diese Verwirrungen am Ende noch führen mögen!

I received a review copy of this book.
I have to say, this was probably the most amusing of all the books in this series so far. The story is a good one, and it's amusing all the way through, not just here and there. The main character advances along his quest line, (with lots of adventures to keep him busy in the process), Outsmarts some annoying little green NPC (sure was happy to see that), and interestingly enough, bumbled his way into completing several side quests.
The series is shaping up to be quite the story arc, and I'm glad I found this one, it's extremely entertaining.

KU Review

Absolute chaos. From start to finish. MC has fortitude for sure. Keeps taking the hits like a champ and keeps going. Such a fun series.

As the title says this is a review for Kindle Unlimited and as such is a reflection of my enjoyment of the book and in no way reflects cost to value analysis.

Pretty okay

Honestly if it weren't for the fact that page 323 (before and a little afterwards) was just bad luck after bad luck I would've enjoyed this book more...shortly after that it gets better so make sure to keep reading it

Wow!

Standard world building LitRPG mechanics

What sets it apart is the interaction with the real world. Well constructed story line and a fun read.
