Elisabeth Hatzi asked Blake Crouch:

I enjoyed very much reading Dark Mater. One of the best books ever. Have you researched quantum physics in order to write this book? Do you believe in a parallel universe?

Blake Crouch Yes indeed, lots of research, and I suspect parallel worlds exist.

I loved Dark Matter. It was the first book of yours that I read and I am looking forward to reading more. What are some of your strategies, as an author, to keep track of the timelines and characters in your stories as you write?
