Right now, I'm reading the thrid shiver trilogy book, Forever, and I am impressed. When it comes to reading, I wouldn't really say it's about the age. Is says teen at the back of the book, but I would say level..5A + ? However, there is as much negativity about the book as there is positivity.
Sex - Trust me, a lot of sexual language is included.. the author, Maggie Stiefvater even said on her youtube channel " I write books about .. werewolves and kissing " XD
Language: Not often, but from time to time may inlude LITTLE swearings such as b-tch, b-stard. Otherwise, she writes something like " I swore, quietly " or whatever, as it is written in the first person. :))
Voilence: It is a book about werewolves.. what do you expect ?
Drugs etc: Cole's band, NARKOTIKA is Albanian for Drugs, and they also take drugs.. so yeah, that explains it all.
Overall, it is.. well, I would say ' fun '. It's a bit like watching a movie, than reading, but does refresh your writing skills only slighlty!
