I think I liked this one a lot better than Fallen. I was afraid after reading Fallen that Luce would have no real personality and be dependant on Daniel. But this book gave Luce a much needed personality so she was someone without relying on anyone else (though it's worth noting that she DID rely on a lot of other people). 
 I was a bit bugged by Luce, but that's more of a personal thing. I kept wanting to scream at her that if she had trusted Daniel for lifetimes, why in THE world would she not trust him enough to wait patiently for 18 days? I mean for cripe's sake, it's only 18 days, you're pretty lame if you can't sit back and enjoy beautiful weather and friends for that long without throwing a hissyfit to your boyfriend. 
 But I digress. 
 I felt that there was a lot of good non action action, which most books lack, but when it came to the real action it was quick and not very descriptive as to what actually happened. I had to go back and reread so things to get a somewhat idea as to what in the world was happening. It was very jumpy when it got to that area. 
 Overall, good. Left me awaiting this coming summer so I can read the next book. I feel like there's a lot that can happen in the next book. I'm excited to see where it goes.
