I think I had different expectations when I picked up this book. I wasn’t expecting a YA novel. Once I got over that realization, however, I thought the story and plot were good, but the character development needed a little work. The best part of the novel was the idea of a rift that goes to multiple different Earths with varying points in evolution and the multiple paths taken by the different versions. The least interesting part of the story, or rather, the part of the story that needed a little more work was with the romance between Ryn and Ezra. There was just something too easy and simple about their instant attraction to each other. I guess I was looking for a little more drama. The setup of the conflict between ARC and the Citadels was very compelling and worth reading the book. I think Ms. Foster has left herself a wonderful opening for the next installment and I look forward to seeing where she takes the story from here. This was a light, easy read and I recommend it.
