This was a pretty standard Young Adult Paranormal Romance novel. The heroine thinks she's normal but turns out to be extra special. There are two hot guys chasing her (one denying his feelings while the other isn't shy about it, of course), and it's pretty obvious who she's going to end up with. Instead of vampires, werewolves, or the usual fare, we have descendants of the Greek gods, who have special powers and are, of course, fighting a war and, of course, our heroine is the one who is supposed to turn the tides. 
 Honestly, some of this book can be pruned. At about the 50% mark, I thought I was almost done, because of how much it dragged. It has to take a screeching halt so that Kris and Nathan can spend a considerable amount of time together to go from the guardian angel/damsel dynamic to having romantic feelings for each other. I can't say for Nathan, but it seems like Kris only likes Nathan because he's hot and he'll always save her from getting killed. Then there's Alec. He exists only to be the third point of the love triangle to tempt Kris, but they'll never end up together. 
 If some of Kris' inner dialogue about how hot Nathan was had been cut, it would have been better. At least she reminds me of a hormonal seventeen year old instead of acting like she's twelve.
