TimeQuake by Kurt Vonnegut, Jr.

Vonnegut fans will enjoy this pseudo-novel that is composed of fragments of a novel Vonnegut wrote but later decided wasn’t sufficiently worthy to be a novel. Yet, he wanted to salvage some of the ideas. The result is Timequake: the best parts of the initial novel presented with introductions and various other thoughts and musings on life.
The plot, which matters even less in this work than in other novels, is about everyone being shifted back in time 10 years and having to relive those 10 years without being able to do anything about it.
As usual, there are some wonderful stories and thought experiments that make you laugh and provide perspective. Enjoy it! Ting-a-ling!
