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.

Started with a slow burn...
Format: Kindle
Well this book started with a slow burn as the author tried to not just teach the MC, Emma, but to everyone reading, a whole new kinda magic system. And it's purdy gimmicky if you ask me. I did like Emma's devil may care attitude when it comes to problem solving. Still it got better after new characters were introduced and Emma managed to team-up. And the story was fun as they work out the intricacies of the system. I am even eager to try the next book to see if it'll enthrall me.
Here's a couple of quotes that amused me:
“You could’ve died, you jerk!” I shake my head with a small smirk. “No, no, it’s pronounced, ‘Wow, that’s amazing, Emma!’ ”
"...the plesiosaurus... plesiosauruses? Plesiosauri? The plessies chase after me..."

Love it! Romance included!
Format: Kindle
Love the characters, love the world, love the series!
The romance aspect turned out to be quite entertaining, definitely a slow burn, which is my favorite and the fact that the love interest is a girl has me cheering. But the story is a litrpg first and foremost and isn’t lacking on anything I look for in the genre. A lot of things about the world are completely original as well. I couldn’t put it down and read through both of the first two books in two days.
To those hating on Katelin… why? I think she’s hilarious and super cute. Also, if you’re confused as to why Emma seems attracted to her even though she’s straight, that’s actually explained in the next book. Pretty clever honestly.
