Enjoyable premise that's poorly written
I don't like giving negative reviews, but at least I will include constructive criticism.
First, have you read Primal Hunter? Because the author obviously has. There are some things that could be considered universal, such as a ranged attack having a PowerShot skill. But when certain specifics start to show up, like poison and alchemy being the core of their cultivation, a gaze attack that stuns people, your internal cultivation being the alpha predator and giving you extra powers because you're superior? That's a little too on the nose. And a companion that says "Ree!"
Next, the writing is simply amateur. More than 9/10 times dialogue ends with "said ."
"I understand" said Sorin.
"We need to leave!" said Lawrence.
"We have them on the ropes" said Stephen.
Almost every time. There are many ways to change up who said what and how but the author does not use them.
There were also a number of punctuation, spelling, and misnaming mistakes. Many of these could have been caught by a common spell checker, let alone a proofreader. It's immersion breaking when person A gets a new skill, but person B uses it, then back to person A speaking about it.
Another bit of the amateurish writing was the flip floppy nature of some of the relationships, namely between Sorin and Marcus. Also Sorin and his servants. I found myself confused as to whether he trusted or hated people depending on the chapter. You know your servants are spying on you, yet you trust them with your deep secrets? Occasionally it is remarked that information is intentionally leaked but all the other times I have to wonder.
The author explains the currency system, having copper, silver, and gold, and the conversion rate. One single time silver is used and every other time currency is mentioned it's in gold regardless if it's a cup of coffee or a library fine. What's the point of a currency system if everything uses the largest denomination of coin?
The power creep is not sustainable. The characters go from barely handling common fodder to fighting well above their rank in short order.
Similarly, world secrets are not kept secret for long. Something happens to Stephen and they make a big deal about keeping it quiet. However, it soon happens to Sorin, and he runs his mouth about everything. Then it turns out that everybody knows about it, besides just the powerful families. And then, and this annoyed me greatly, everyone else gets the rare, secret, hush hush power that was supposed to be a big deal. Doing that makes it not a big deal at all. And at this point in the story you can tell, due to the lackluster writing, that this thing is going to happen to everybody; it's just a matter of time. The entire story became extremely predictable as the foreshadowing was not subtle.
I liked the touching of Greek mythology, and how the world is shaping up, but I can't stand the writing. At about 80% I was hate-reading; I had to finish the book but I was not enjoying it. Everything was predictable and the power was skyrocketing to the point of not being fun. A lot of "of course they do" moments. Of course that one gets a hero power. Of course that one can fly and go invisible. Of course they're able to do the thing that no one else can and should kill them.
Sadly, I cannot continue this series. As I said, the idea behind the world sounds interesting, but the writing is simply not entertaining enough to make me want to explore where it's all headed.
