The beginning was promising, but then the story felt dragging, and all of a sudden there was this action-packed ending where too much happened yet it felt too convenient as most of the loose ends were given a little too perfect resolution. I really liked the world and its vibes, but I wish the story didn't read so much like a childrens' book — I do know that this is YA, it's not supposed to be as 'serious' as 'adult' books, but most of the YA I've read hasn't felt like this, even the first Harry Potter was way better in that sense and it's supposed to be for literal children. 

I never understood why Evangeline was so deeply in love with Luc, their (past) relationship wasn't explained nearly as much as it should have. Also the 'unnecessary' guys (others than Jacks) were taken care of a little too conveniently — I mean, could you maybe have resolved the unspoken relationship issues by some other way than killing off Apollo and making Luc become a vampire? Yes, you don't have to think about a guy if he's a literal monster or doesn't exist anymore, but having them discuss things deeply with Evangeline would have helped this book reach the (emotional) maturity it so desperately needed.
