I really liked this book even though it took me a bit to get into it. I gave up sleep so I could read it, and I am annoyed that I have so long to wait for the next one. I hope it isn't going to be a series with each installment featuring a different couple though. I very much want to read Roar and Liv's story, but I need to finish Aria and Perry first.
Also, I was never too terribly bothered by not getting an explanation about aether, lol. :)
