Last week I asked readers to help me remember the name of a science fiction book centered around an OCD man who has to carefully follow a specific routine or else reality unravels, an event that leaves the world subtly, or sometimes not so subtly, changed.
The book is called Resonance, and I re-read it this weekend. I had forgotten a lot of it but it really is a terrific, under-hyped book. There is real suspense as the unraveling of the world accelerates and our hero starts to better understand exactly what is going on. What I enjoyed the most was how there were two people in the book who had special, err, powers but who initially totally interpreted what these powers were or how they worked.
I have never seen a paperback version of it, but commenters tell me you can find it in the Baen free library (if so, that is a screaming deal because this is a pretty good book) and it is available on the Kindle.
