I'm a big fan of that series (the second one being my favorite), but I also get where you're coming from. I felt that, as books went on, they became more about the Science-Fiction concepts and less about the characters. I do hope you come back around to it though, as I thought that the second half of The Dark Forest was better than the first.
I'm reading the second Warhammer Horus Heresy book and I was expecting this and the first to be a bit poorly written and like fan fiction but they are actually excellent and elegantly written.
It's a stark difference from the meandering and waffle of the wheel of time books I've been consuming.
Currently reading Lolita, after I have book 3 of the Millennium series and book 3 of the expanse.
Also begrudgingly waiting for the next Crescent City and ACOTAR books, we have a mini book club at work and I've already invested too much time into these books to give up now lmao
Slowly working through House of Leaves. I haven't read a physical book in many years so it is difficult, and not as convenient as my ereader because I can't just pull it up onmy phone when I have a few minutes to spare.
I'm reading 4 at the moment, but the one I'm most into is American Gods by Neil Gaiman. I love his books, but struggled with this one in the past. I'm having a good time reading it now, though.
