I don’t see a problem with reading slowly. I read quickly, but I’ll slow down a bit sometimes because every once in a while I forget important plot points that happened earlier in a book due to reading a little too fast and not being able to remember every single notable thing that happened in the last 50 or so pages that I read in under an hour, especially if it’s a book that’s extremely plot heavy.
I’m close to being halfway done with the series and I’m loving it so much. Completely lives up to the praise it receives.
