This book grew on me. I started it thinking it's just okay and then it became better and better. The world reminds me a little of another book I read where these different worlds are connected by bridges, etc. These are countries instead but each country starts out so different until hatred takes over and they start falling one by one. The romance is a little different - the couple are "moon bound" but they have a huge wait because of the age difference so Torrant finds romance in the short term supposedly with other people, male and female. I enjoyed this book a lot and would recommend it.
