Isaac loved to read spending all of his free time reading and learning. His dream was to be able to work in a library but was unable to afford the years of college to achieve that dream. He worked at a grocery store making minimum wage and barely scraped by. All of that changed when he received a package in the mail.

Writing Quality: It... isn't good. While the basic grammar (the word-by-word grammar) is fine, trying to keep in mind when [MC] or [other characters] are talking is a genuinely tough task, due to the lack of dialogue marks (the "[words of dialogue]"). And often, even reading is hard, due to a severe lack of commas... Because of that, I found myself skimming over the paragraphs. Author, feel free to refer to some comments I left on the chapters. I can give a bit of an extra explaination, if needed.

Story Development: Too early to judge. I did like the concept, though.

Character Design: It's... I don't know how to feel about it? We're presented to [MC], an everyday man who had his dreams crushed by society's cruel rules... Only for him to react calmly to all of the events taking place in the Library, with the ones that stood out to me being the tentacles, and the bloodline recreation. In the former, [MC] had some panic, but almost forgot about everything right after?? With something similar happening with the bloodline recreation. Both the [MC] and his "best friend" had a similar reaction to that one, with them even being able to joke and flirt casually around *after* having gone through a potentially life-and-death experience. A horribly painful one, at that.
I was going to rate this 3/5 because of William and the former Librarian Keeper (Both of which generated some interest for me), but I decided against it. 

Update Stability: By WN's standards (consistent 7-14 chapters per werk), this is low. You're barely starting, though, so I'd say this is one of the easier things to fix.

World Background: Up to chapter 7-8, there's little information. A few names were dropped in the dialogue, but nothing explained in depth yet. Only reason why I'm giving it 3/5 is because the Library itself is interesting.

So, yeah. I don't have much else to say here  as I've already said everything in the previous paragraphs... Wait, nevermind, I do.

Consider changing some of the tags, as certain things might be seen as deal-breakers for many. (An example possibly being the lack of an LGTB tag. This one is a genuine piece of advice, so you can avoid waking up to a bunch of insults and threats over having a kiss between two best friends.)

... That's about it. Have a good day/night, readers/author!
