Let me be honest, Foundation book series kinda sucked to me. I read them when I was 12 year old grabbing them from my fathers library, I was able to read everything back then, hell I was able to get through about 250 pages a day no matter the book quality which is propably why I was able to get to the fourth book of Foundation before just dropping it out of sheer boredom,
The series is pretty good so far btw. The one time I am thankfull for very loose book adaptation.
