I wouldn't have read this if it wasn't the pick of the month of a book club I'm in. The first 9% was incredible hard to get through, it was downright depressive. And then I got a nice little spark of excitement as the MC finally got invited to Tower of Somnus (I HAD CHILLS!). Just to have to struggle through a specific character that decided to be a total asshole.

Kat allowed things I never would, and I was furious for her sake. I might have dropped the book here, if not for the book club.
Alas, I pushed through, and said character fell away and I fell in love.

I love the system, I love the random skill drops from certain mobs, I love the random rewards, I love the ingame skills becoming part of their real world. I love that I didn't know who the "bad guy" was at the first incident, but had a pretty good guess at the second.

Also, there is a lot of time skips, and a lot of perspective changes between the "in-game" and the "real-life". Both of these are things I normally hate in my litrpg. But the timeskips (that was sometimes up to a week, but often just hours of grind) felt fluid, I felt I got enough description of combat and gains were slow enough that the skips felt natural. (in fact, you only level up here when you go up a floor. So the MC is only level 2 at the end).

And the perspective changes? I was engaged wherever the MC was, both in the tower and in her city. I was never annoyed at the change, I loved it.

My biggest complaint, other than the beginning, would probably be that Tower of Somnus paints a colorful picture full of aliens and weird monsters. But description of these was often lacking, I'd have loved more details on how things looked. But I loved this.
