I had the privilege of reading Walter's next book, Migration: Knowledge and was so drawn in that I had to read this one to catch up. I was not disappointed. The story draws you in an you become a part of the team with Rhys and Jason and their Military liaison, Ms. Franks. The story draws you in and the imagery keeps you hooked. In a sense, I'm glad I read the new one (publishing October 1!) first because it gave me so much more that way.
Do yourself a favor, read this series. The concepts are not that far flung and the geography makes this relateable. You won't be able to put either one down.
