Битката за Фондацията

It's noticeable that this book was written way later in Asimov's days. The pace is different, the story development is different. The book itself is quite good - it gives a lot of details that fit right in place if you're reading it last.

But there are some details that don't match the puzzle perfectly. It feels like he never had the chance to fully develop those storylines, which are out of place. Some of those would be Doris's death, as it's never known why would anyone like to hurt her, why Doris went to the meeting in the first place, are the mentalists having different functions and why those mentalists had to move away.

Anyways, it was a nice closure and I was happy I've read it!
