Conclusively the book is an amazing read, is great for re reading too and proves that the old vampires who can't super model can still be interesting. I recommend this book for children and teenagers. Any older and you might just find this too clichéd and you might just hate the main character too much.

Definitely buy it from Waterstones :)
Ohh and one last tid bit, DO NOT watch the movie.
