Amazing, different, success.
Format: Kindle
First let me say that this book (series) was not something I normally read. I prefer LGBT books written by women, but I also had no idea what a LitRPG was.
I started the book cautiously, I found myself a little disappointed that it was under LGBT but the main character was into her co-worker. The co-worker was a dude. But I kept reading and I was surprised by how I got into the fact that it was sending her into a realm where she was basically a character in a video game. Completing tasks to earn points, leveling up, gaining stats.
Now I’ll be honest, some of the information in this book (and the rest of the series) flew straight over my head. The author is definitely far more intelligent than I, and probably most average people lol.
Finally, the characters are actually well developed and have their own unique personalities. With Emma’s leadership qualities she helps her group of new friends survive and turn into badasses. In the following books you can see how they each change and take on different roles over the course of their trials.
This first book was great, it got me hooked. But it gets even better as time goes on! I have read this series so many times that I basically know it by heart. It’s that good.
I recommend you read this, and the 5 other novels in the series. Also, check out the authors website and Patreon for sure. He’s currently working on a new series and posts chapter updates in Patreon posts.
PS. I only leave reviews on books that wow me. :)

Comes Off Naturally
Format: Kindle
Unnatural Laws introduces a few wrinkles to the isekai LitRPG template and makes a comfy niche for itself.
First, as the title implies, it introduces a few variations to the laws of physics. Water has higher self-cohesion, breathing can be weaponized, gravity's parameters work differently, etc.
Second, the book includes the "forced participation in a training/puzzle facility" subgenre. Instead of a short tutorial arc, the first book ends well before winning free of the deadly training scenarios.
Third, the "portal" mechanism by which folks are yoinked into a new reality. It is implied that the "kidnapped to another world" setup will continue to be important to the plot, where in most other Isekai it doesn't particularly matter how or why the MC got yoinked...it only matters that it happened.
The most important things to me are characters. And these characters work! The MC is snarky, tough-minded, and takes charge. In a romance novel dust jacket, that description would already have me nauseous in anticipation of a vapid young woman who "zings" when silence would serve and who only appears "tough" and "take charge" because all of the other characters react to her that way. Not in this book! In this story, it's real and it's working for me.
The secondary characters are also real to me. A young woman who low-key flirts with everyone (unconsciously?) and gets preferential treatment. An earnest young man who flees from anything he considers "work"...but will happily pour himself into crafts he enjoys. And others that I can only encapsulate even worse, so I won't try! There is plenty going on and plenty more to uncover. I thoroughly enjoy watching them interact and cooperate to navigate their new circumstances.
Other things that are present and well-done, even if they don't stand out quite as much:
- An assistant AI with secrets to keep
- An interesting LitRPG system, blended with cultivation
- A teaser for a well-built new world
- A germinating romantic relationship
If you enjoy the Isekai genre, the only thing that should make you pause before buying this: It's light on combat. Plenty of action, mind you, but most of it isn't combat.
If that doesn't bother you (as it doesn't bother me), then you should pick this up.
=====
EDIT: After reading 5 books, I like this series even better. At this point, I'd revise the subgenre to be "death games" and mention that the death games don't finish until the very end of book 4.
The "light on combat" label expires with book one...there's plenty of combat after that. It is both well done and inventive!
Lastly, I suppose this could be classified as YA fiction. Political landscapes and broader implications are hinted at, but you rarely get a look at them before they arrive and change the landscape. That said, I'm no spring chicken and I enjoyed these books a great deal.

Literally stayed up all night reading this.
Format: Kindle
A classic litrpg, but without some of the lazy tropes often used. Refreshing and familiar at the same time.
The worldbuilding is great, the system is intriguing, the supporting cast is fun, and the MC is best summarized as a college student out of her depth staving off constant threats of death through the sheer bullheadedness of refusing to die.
Romance isn't a major theme in this story, but threre is a hint that the MC isn't quite as straight as she believes.
The writing is consistent and the narrative rarely drags, and why are you still reading this review? Go read the book.

Loved it!
Format: Kindle
I'm not sure what I was expecting when I started reading this book, but it definitely wasn't what I got. And, what I got was so much better! The idea of large groups of people just being taken from Earth on a schedule and yet the general population still having a rather blase attitude about avoiding large crowds is something that, 2 years ago, I would have said was unrealistic. After living through 2020, I now think it's incredibly realistic. As is the reaction had by a lot of the ones taken with Emma - well, before the coughing started, anyway.
As for the trials. Holy crap! I can't imagine having to go through those, but I loved Emma's absolute determination to make it through them so she can (somehow) make it back to Earth and see her family again.
Also, I was pleasantly surprised at how well the first trials section went, as it can be very difficult for authors to maintain a flow when there's one person. Having Suri there for conversations helped, but Wells did a masterful job there.
Then we get to Hub Two and the difficulties there, and man! While I do hope that Emma doesn't have to keep taking so many crazy risks, her sheer determination to make it through works so well. Even though she clearly has plot armor that prevents her from dying, all the close calls - and the ways she gets out of them - are done really well. None of them seem outlandish or unrealistic, at least to me, which I greatly appreciated.
I am definitely looking forward to reading book 2.
