I finally got around to finishing this series XD I've had the first 4 books for a couple years but just this summer got the other 2 from work and finished it. 
 From the very beginning I've loved how fast-paced and addictive the series is. Once you pick up the first book, you won't be able to put it down until you're done with the series. It deals with a lot of paranormal, time travel, and moral/spiritual issues, which are as fascinating as they are heart-wrenching. Ever starts out as a jangled, grieving character with a very negative outlook on life, but as the series goes on she grows into a calm, self-assured young woman, which I think is very inspiring. One of the main messages of this series is to learn to let go and to remain positive, to have faith in yourself, no matter what happens, which is pretty powerful stuff. The very end of the series was unexpected, but I didn't find myself jilted by it. It all seemed fitting. 
 I'm definitely going to have to pick up the last 2 to round out my collection. Again, this series is very fast-paced and addictive. It's a good balance of plot and character driven. I'd recommend this series to young adults who like a little bit of paranormal with their romance.
