Based on the first half I would give it one star, possibly not even that. Well not possibly because it's not possible but still. The first half was cringey insta-luv at its finest and very little development in both plot and characters. 
 The second half however really took me by surprise and I have some begrudging respect for the sudden massive change in where the story was going. Maybe I was completely brainwashed by the first halfs complete crapness but i was really caught off guard when things got bitey. 
 The protagonist was unbearable through the beginning with the completely weird and unnecassary swooning and shit after meeting Lucas for the first time. When she grew up a little she became more likable and that I guess makes her a posterchild for character development, though I wouldn't take it that far. 
 The secondary characters were in a lot of ways more interesting than our little protagonist so I'm looking forward to reading about them all later. I have to say, the book does create a massive conundrum that I am very interested to see solved. I have absolutely no idea where the plot will go next. Some parts of the book were painfully cliched and obvious, especially when regarding Lucas, but other things completely took me by surprise. I would love to have given this book more, and its a massive credit to the second half that i do. But the first half was too mindumbing and brain rotting for me to be cool with that.
