Book 41 of 2015 is Spin by Robert Charles Wilson.
The movie Interstellar has done for science fiction books what Hunger Games did for teenage post-apocalyptic fiction. Everyone is writing variations of it. Like The Fold, Spin is another sci-fi tale with temporal challenges.
This book is too slow and not for any good reason. The character development is sloppy and I felt most sad when an alien die than a human.
3.5 million billion years of 5.
Should I read this? No. There are better books in this genre.
What did I learn? We all fall and we all land somewhere.
