I'm giving this one a rating of 3. I loved this book, and though I had some teeny tiny problems with it, I definitely enjoyed this.
It was interesting about their powers and the future Portland. Like, who doesn't like to read about portals and flying for transportation? Basically, I like the world the author built up. But for the plot itself, it's nothing exciting. It is exciting at the end, but in most parts of the book, it was practically centered on the romance and drama.
For the characters, I thought that Echo and Connor were cute, and I loved their antics, especially that prank they pulled on Raquelle. I've grown to like them (and even the other characters, mostly those from the future), but I don't really care that much about them.
This was an enjoyable read, but if you were expecting action, you'd be disappointed as it's mostly romance and drama.
