I love the series, I really do but somehow this last instalment feels disjointed. The unrealistic reactions of the characters in particular. 
 It may be the switching POV's however Caleb's POV side story previously was a great addition and read a lot smoother then it does this time around. 
 The writing just does not flow the same, the dialogue more of the previous and shallower then I have come to know these characters.. since when does she care about her weight for one, considering the first book she chastises her dad for reprimanding her on eating sweets and tells the readers she has absolutely no qualms with her image to now all of a sudden having that in her thought pattern out of the blue does not call for a true representation. 
 It is as if the strong lead has completely vanished. The reckless stupidity of her just as ridiculous friendship with her BF that leads to even more weird reactions from said BF boggles my mind. I know this is fiction and Im all for a bit of shrugging off certain things.. but if your BF/daughter is missing for a day after a wreck is found, you do not ring people for a funeral nor do you call off a search after a day. Fictional world or no, that is human behaviour we are talking about. 
 Anyhow. It feels like a piece of bad fanfiction to me as if this is the first instalment and it will only get better instead of to other way around. 
 I see that there is a 5th book in the making which I really hope will redeem the series again for me..
